About This Guide
The AppleScript Finder Guide: English Dialect describes the commands and object classes defined by the Finder for use with the English dialect of the AppleScript language. The Finder scripting software allows you to write, record, or run scripts that control actions in the Finder such as opening and closing folders and manipulating files.
Audience 0
This guide is for anyone who wants to record or write new scripts or modify existing scripts that control actions in the Finder.
Before using this guide, you should have installed AppleScript with the Installer program. You should also be familiar with the AppleScript Language Guide: English Dialect, which describes the English dialect of the AppleScript scripting language, the AppleScript Scripting Additions Guide, and Getting Started With AppleScript.
Macintosh software developers who want to make their programs scriptable or recordable should also refer to Inside Macintosh: Interapplication Communication.
Organization of This Guide 0
This guide contains three chapters:
Chapter 1, “Introduction to Finder Scripting,” introduces Finder scripting and describes how to record and modify simple scripts.
Chapter 2, “Finder Objects,” provides definitions for all Finder object classes.
Chapter 3, “Finder Commands,” provides definitions for all Finder commands.
ix
P R E F A C E
At the end of the guide are two appendixes and an index.

Other AppleScript Dialects 0
A dialect is a version of the AppleScript language that resembles a particular human language or a programming language. This guide describes the terms defined by the Finder for use with the AppleScript English dialect. Versions of the Finder for use with other dialects work the same way but define terms and syntax appropriate for those dialects.
Conventions Used in This Guide 0
Words and sample scripts in monospaced font are AppleScript language elements that must be typed exactly as shown.
Here are some additional conventions used in syntax descriptions:
language element
Plain computer font indicates an element that you must type exactly as shown. If there are special symbols (for example, + or &), you must also type them exactly as shown.
placeholder Italic text indicates a placeholder that you must replace
with an appropriate value. (In some programming languages, placeholders are called nonterminals.)
[optional] Brackets indicate that the enclosed language element or
elements are optional.
(a group) Parentheses group together elements. If parentheses are
part of the syntax, they are shown in bold.
(a group). . . Three ellipsis points (. . .) after a group defined by
parentheses indicate that you can repeat the group of elements within parentheses one or more times.
[optional]... Three ellipsis points (. . .) after a group defined by
brackets indicate that you can repeat the group of elements within brackets 0 or more times.
a | b | cVertical bars separate elements in a group from which
you must choose a single element. The elements are often grouped within parentheses or brackets.

Introduction to Finder Scripting 1
Finder scripting refers to the use of AppleScript and an application such as the Script Editor to write, record, or run scripts that trigger actions in the Finder. This chapter introduces Finder scripting. It also describes how to
record your actions in the Finder in the form of a script
modify recorded Finder scripts
begin writing Finder scripts
This chapter assumes that you know how to use the Script Editor application to run a script. It also assumes that you understand how commands and object names can be combined in Tell statements to describe actions performed by an application. If these concepts are not familiar, read Part I of the AppleScript Language Guide before reading this chapter.
Installation 1
If you obtained the Finder scripting software with the AppleScript Scripter’s Toolkit, you can install it by running the Installer program on the AppleScript Setup disk. After the Installer opens, click the Customize button, then select the item named Finder Scripting Software and click Install. If you obtained the Finder scripting software on a disk that updates an older version of the AppleScript Scripter’s Toolkit, run the Installer program that’s included on the update disk and click the Install button after the Installer opens.
Finder scripting requires System 7.1 or later versions of system software. Versions later than System 7 Pro (System 7.1.1) include the Finder scripting soft­ware, which is installed automatically when you install the system software.

Introduction to Finder Scripting
IMPORTANT
Finder scripts that return a lot of information may need as much as several hundred kilobytes (K) of free memory to work correctly. To see how much memory is currently free, activate the Finder, choose About This Macintosh from the Apple menu, and check the number labeled Largest Unused Block in the About This Macintosh window. If a script you’ve used successfully stops working, try quitting one or more applications to make more memory available.
What Is Finder Scripting? 1
The Finder is a specialized application that controls the Macintosh desktop: the working area of your screen where you can use the mouse and the keyboard to open and close folders, manipulate files, and inspect or alter various aspects of the computer’s operation. Finder scripting involves performing the same kinds of tasks, except that instead of triggering actions with the aid of the mouse and the keyboard, you trigger actions from scripts.
The Finder is both scriptable and recordable. A scriptable application is one that can respond to commands sent to it when another application, such as the Script Editor, runs a script. A recordable application is one that uses Apple events to report user actions for recording purposes. When recording is turned on, the Script Editor creates statements corresponding to any significant actions you perform in recordable applications, including actions you perform in the Finder. By recording or writing scripts that control the Finder, you can automate many file management and networking tasks that you would otherwise have to perform manually.
For example, the script that follows copies the items from a folder on the startup disk to a folder on a different disk. Instead of opening all the folders by double-clicking them then dragging the contents of the AppleScript folder to a storage disk, you can run the script.

What Is Finder Scripting?
CHAPTER 1
Introduction to Finder Scripting
tell application "Finder"
copy items of folder "AppleScript" of folder "Projects" of ¬
startup disk to folder "Backups" of disk "Storage"
end tell
This script consists of a three-line Tell statement that names the Finder applica­tion running on the local computer as the target application. (The ¬ symbol is a “soft” return; it tells AppleScript to treat the line it’s on and the line that follows as if they are a single line.) As far as AppleScript is concerned, the Finder is just like any other scriptable application.
Like other scriptable applications, the Finder defines commands that you can use in scripts to describe actions. Some of these are standard application commands, such as Copy, Open, Print, and Move, that can be used with most scriptable applications. Others are commands unique to the Finder, such as Eject, Put Away, and Restart. The Finder also defines classes of objects on which actions can be performed, such as files, folders, and disks. Most of these object classes are unique to the Finder.
The copy command in the preceding example acts on the objects described by the reference items of folder "AppleScript" of folder "Projects" of startup disk. The folder AppleScript is located at the top level of the folder Projects, which located at the top level of the startup disk. The term items refers to all objects in the AppleScript folder, including files, other folders, suitcases, and so on. Any object in the Finder can be identified from within a script as long as its container and if necessary the container’s containers are also identified.
By using AppleScript features such as Repeat statements and other control statements, you can create more complex scripts that take different actions depending on the outcome of one or more tests. For example, the script that follows checks all the disks of a specified computer for the presence of a folder called Back Me Up. Whenever a disk contains such a folder, the script creates a folder on a storage volume and copies the contents of Back Me Up to that folder. (The storage volume must be mounted on the remote computer for this script to work correctly.)
What Is Finder Scripting? 3
CHAPTER 1
Introduction to Finder Scripting
tell application "Finder" of machine "Macintosh IIci"
repeat with i in every disk in desktop
if folder "Back Me Up" of i exists then
set folderName to name of i & " " & ¬
day of (current date) & " " & time of (current date)
set newFolder to make folder at ¬
disk "Storage" with properties {name:folderName}
duplicate (items of folder "Back Me Up" of i) to newFolder
end if
end repeat
end tell
The Repeat statement in this script applies the statements it contains to every disk on the desktop of the computer named Macintosh IIci. The If statement within the Repeat statement checks each disk for the presence of a folder called Back Me Up. If the folder exists on a disk, the second line of the If statement sets the variable folderName to a string that consists of the disk’s name, the day of the month, and the time in seconds since the beginning of that day, thus ensuring that any other backup folders created from the same disk at a different time will have slightly different names. The rest of the If statement creates a new folder with the name assigned to folderName on a storage disk and asks the Finder to duplicate the items in the Back Me Up folder to the new folder.
As you can see, scripts that control the Finder use familiar terms like folder, disk, and desktop as well as standard AppleScript terms like of, repeat, and tell. Chapter 2, “Finder Objects,” describes all the terms the Finder defines for objects, and Chapter 3, “Finder Commands,” describes the terms it defines for commands. You can use these chapters as references when you need detailed information about specific objects or commands. However, the easiest way to learn how to use the scripting terminology defined by the Finder is to record your actions in the Finder and examine the resulting script.
The next section describes how to use record and edit scripts that control the Finder. When you see how the Finder uses its own terminology in recorded scripts, you can begin writing your own scripts from scratch.
4 What Is Finder Scripting?
CHAPTER 1
Introduction to Finder Scripting
Recording Actions in the Finder 1
You can record almost any actions in the Finder that involve manipulating Finder windows or icons: for example, opening folders, copying files, or changing View settings. To record actions in the Finder, click the Record button in the Script Editor application, then activate the Finder (by clicking on the desktop or choosing Finder from the Applications menu) and perform the actions that you want to record.
For example, suppose you like to have certain Finder windows arranged next to each other on the desktop when you’re working on financial matters, so that related files, alias files, or applications are easily accessible. To record the arrangement you want, follow these steps:
1. Open the Script Editor application.
2. Click the Record button.
3. Activate the Finder by clicking on the desktop or choosing Finder from the Applications menu.
4. If any Finder windows are currently open, close them all by holding down the Option key and clicking the close box of the active window.
5. Open, resize, and arrange the windows whose positions you want to record.
6. When you’re satisfied with the arrangement of the desktop, activate the Script Editor again and click the Stop button.
The recorded script should look something like the one in Listing 1-1 on page 6.
If you save your recorded script as a script application, you can arrange the windows the same way at any time by double-clicking the script’s icon in the Finder. The Finder responds by closing any windows that are currently open and opening and arranging windows as specified in the script.
Recording Actions in the Finder 5
CHAPTER 1
Introduction to Finder Scripting
Listing 1-1 A sample recorded script
tell application "Finder"
activate close every window select startup disk open selection set position of window of startup disk to {4, 43} set size of window of startup disk to {369, 464} select folder "Financial" of startup disk open selection set position of window of folder "Financial" of startup disk to ¬
{378, 43}
set size of window of folder "Financial" of startup disk to ¬
{200, 155} select folder "Letters" of startup disk open selection set size of window of folder "Letters" of startup disk to ¬
{257, 385} set position of window of folder "Letters" of startup disk to ¬
{379, 222} set size of window of folder "Letters" of startup disk to ¬
{200, 286}
end tell
Modifying Recorded Scripts 1
You can often modify a recorded script to suit new circumstances. For example, you could adapt the script shown in Listing 1-1 for use with an external hard disk rather than the startup disk by changing the term startup disk to disk "nameOfDisk" throughout the script, where nameOfDisk is the name of the hard disk on which the folders Financial and Letters are located.
Or suppose you want to make sure the Finder opens each window specified in Listing 1-1 with a specific view selected in the Views menu. One way to do this might be to place the insertion point after the last line of the script in the script
6 Recording Actions in the Finder
CHAPTER 1
Introduction to Finder Scripting
window, turn on recording, choose the settings you want for each window from the View menu, and turn off recording. Any significant changes you make to the windows’ views will be recorded; however, if some of the View settings for some of the windows are already set the way you want them, the Finder won’t record the action because nothing changes as a result.
A more reliable approach is to add lines to the recorded script that set the View settings. To do so, you must know how to tell the Finder to set the view of a window.
The easiest way to learn how to describe an action in the Finder is to try recording the action in a sample script. To learn how the Finder sets a window’s view, follow these steps:
1. Open a new script window in the Script Editor by choosing New Script from the File menu.
2. Click the Record button.
3. Activate the Finder by clicking on the desktop or choosing Finder from the Applications menu.
4. Change the Views setting for one of the Finder’s windows.
5. Activate the Script Editor again and click the Stop button.
The recorded script looks something like this:
tell application "Finder"
activate set view of window of folder "Financial" of startup disk to name
end tell
The third line of the recorded script sets the View property of the window for the folder Financial to name. You can now use this line as a template for setting the views of folder windows in a script. For example, to modify Listing 1-1 so that the windows will always open in specific views, you could add these lines just before the last line (that is, before end tell):
set view of window of startup disk to icon set view of window of folder "Financial" of startup disk to name set view of window of folder "Letters" of startup disk to size
Recording Actions in the Finder 7
CHAPTER 1
Introduction to Finder Scripting
After you run the new script, the windows have the views specified in the script even if you’ve previously changed them.
To modify recorded scripts or create new scripts that control the Finder, you may need to look up the definitions of some of Finder terms. Like any scriptable application, the Finder contains a dictionary of the AppleScript terms that you can use to control the application. To open the dictionary, drag the Finder’s icon over the icon of the Script Editor, the script-editing application that comes with AppleScript. If you run across an unfamiliar word in a recorded script, you can look it up quickly in the dictionary. If you need a comprehensive definition with examples, look up the term’s entry in this book.
Simplifying Recorded Scripts 1
As is often true of scriptable applications, the Finder allows you to express the same action in several different ways. Recorded scripts are precisely worded so as to avoid ambiguity in variety of circumstances. In the script shown in Listing 1-1 on page 6, however, there is no need to specify the folder and disk to which a window belongs. If you wish, you can specify a window by name only:
set view of window "Letters" to size
To work correctly, the preceding statement must be contained in a Tell state­ment that names the Finder as the target application, and the window named Letters must be open. The container for a Finder window is always the Finder itself. If more than one window named Letters is open, the Finder changes the View property for all windows with that name to size.
The previous section described how to add three lines at the end of the script shown in Listing 1-1 that set the window’s views to different values. If instead you want all the windows opened by that script to have the same view, you could add just one line:
set view of windows to name
The plural form windows identifies all open Finder windows.
After opening a window, the recorded script in Listing 1-1 adjusts the window’s Position and Size properties separately. The terms Position and Size name two different properties of a window. Each property consists of a list of two
8 Recording Actions in the Finder
CHAPTER 1
Introduction to Finder Scripting
integers. For the Position property, the two integers specify the coordinates of the upper-left corner of the content region of the window (the portion of the window that displays its contents; the title bar and scroll bars are not part of the content region). For the Size property, the two integers specify the vertical and horizontal dimensions of the window’s content region.
Instead of adjusting these properties separately, you can adjust them at the same time by setting the Bounds property. The value of the Bounds property is a list of four integers that specify the coordinates of the four corners of the window’s content region. The first and second integers are identical to the value of the window’s Position property. The third and fourth integers can be obtained by adding the first and second integers of the Position property to the first and second integers of the Size property, respectively.
You can easily obtain the bounds property of a window by asking the Finder for it. Just activate the window and run a script like this:
tell application "Finder"
bounds of front window
end tell
--result: {4, 43, 373, 507}
If you wish, you can rewrite a script like the one in Listing 1-1 using the Bounds property instead of Position and Size:
tell application "Finder"
activate close every window open startup disk set bounds of window of startup disk to {4, 43, 373, 507} open folder "Financial" of startup disk set bounds of window "Financial" to {378, 43, 578, 198} open folder "Letters" of startup disk set bounds of window "Letters" to {379, 222, 579, 508}
end tell
Although this simplified version of the script in Listing 1-1 won’t run appreciably faster than the original, it is easier to read. In a longer script, using succinct statements can improve performance.
Recording Actions in the Finder 9
CHAPTER 1
Introduction to Finder Scripting
Writing Scripts That Control the Finder 1
You can use a variety of techniques in scripts you write yourself that you can’t use in recorded scripts. For example, suppose you have several different window arrangements that you like to use, and they tend to evolve and change. Instead of recording a series of scripts, you can write a single script that allows you to perform one of two actions: take a snapshot of the current window arrangement or restore the most recently taken snapshot.
To write a script that performs these tasks, you need to know something about script properties, variables, the Display Dialog scripting addition, If statements, and Repeat statements. For more information about these AppleScript features, see the AppleScript Language Guide and the AppleScript Scripting Additions Guide.
Listing 1-2 shows an example of such a script. It begins by declaring two script properties, boundsAll and refsAll, that hold the windows’ bounds and references to the objects the windows belong to when the script takes a snapshot. At first these properties consist of empty lists. When the script takes a snapshot of the current windows, these properties “remember” the windows’ bounds and references until a new snapshot is taken or the script is recompiled.
After declaring its properties, the script uses the Display Dialog scripting addition command to display a dialog box. The dialog box asks the user to make a choice and displays two buttons: Restore Old Snapshot or Take New Snapshot. These buttons control which of two parts of the If statement that follows runs next.
If the user chooses Take New Snapshot, the second part of the If statement (beginning with else) takes control and stores the bounds and references for the open windows in the boundsAll and refsAll properties. If the user chooses Restore Old Snapshot, the first part of the If statement closes all the windows that are currently open and uses the values stored in the properties to identify the items whose windows are to be opened, open their windows, and set the windows’ bounds. These actions are accomplished with a Repeat loop that acts on one item and its window at a time.
10 Writing Scripts That Control the Finder
CHAPTER 1
Introduction to Finder Scripting
Listing 1-2 A script that either takes a snapshot of the current window arrangement
or restores a previously stored snapshot
property boundsAll : {} property refsAll : {}
set dialogResult to display dialog ¬
"Restore old snapshot or take new one?" ¬ buttons {"Restore Old Snapshot", "Take New Snapshot"}
if button returned of dialogResult is "Restore Old Snapshot" then
tell application "Finder"
close windows set increment to 0 repeat (number of items in refsAll) times
set increment to increment + 1 set i to item increment of refsAll open i set x to item increment of boundsAll set bounds of window 1 to x
end repeat
end tell
else
tell application "Finder"
set boundsAll to the bounds of every window set refsAll to the item of every window
end tell
end if
To keep this script handy, store it as a script application on the desktop. When­ever you want to record or restore a window arrangement, double-click the application’s icon. If you want to be able to switch back and forth between several window arrangements, duplicate the script and use each copy to create and store a different one.
Writing Scripts That Control the Finder 11
CHAPTER 1
Introduction to Finder Scripting
Listing 1-3 shows another script that uses the Display Dialog command. This script automates a couple of tasks that network administrators often have to perform: adding a new user and adding a drop folder for that user.
Listing 1-3 A script that adds a new user to the Users & Groups control panel and
adds a drop folder for that user to the startup disk

end tell
12 Writing Scripts That Control the Finder
CHAPTER 1
Introduction to Finder Scripting
Unlike the script in Listing 1-2, the script in Listing 1-3 consists of a single Tell statement, and the Display Dialog command is invoked from within the Tell statement. The dialog box asks for the name of the new user and stores it in the variable newUser. The three statements that follow open the Users & Groups control panel and use the Make command to create a new user object with the name stored in newUser.
The rest of the Tell statement consists of a series of Set commands that create a new folder on the startup disk with the new user’s name and set the folder’s owner and group and its sharing privileges. The owner and members of the Department Group have all sharing privileges set to true. The guest privileges See Folders, See Files, and Make Changes are set to false, false, and true respectively, so guests can drop items into the folder but can’t open it. These privileges are signaled to guests by a belt around the folder and a small black arrow above it.
For the script in Listing 1-3 to work correctly, file sharing must be turned on and the computer on which the script is running must have a group named Department Group. You can modify that name or other settings in the script to suit your own purposes. You can also modify the script in a variety of other ways. For example, you can add an If statement that checks for the presence of a particular group and if necessary creates the group before creating the new user.

Finder Objects 2
This chapter begins with a summary of the format used in object class defini­tions and an introduction to the Finder application object, the outermost container for most other Finder objects. The last section of the chapter provides complete descriptions of the object classes defined by the Finder.
Using Object Class Definitions 2
Object class definitions describe what objects that belong to a particular class have in common. Each definition contains at least five kinds of information: properties, element classes, commands handled, default value class returned, and one or more examples. These categories are briefly described here, using examples from the definition of File that begins on page 61.
For a more detailed discussion of object classes and references to objects, see the AppleScript Language Guide.
Properties 2
A property of an object is a characteristic that has a single value, such as the name of a window or the modification date of a file. Properties are contained by objects in much the same way that elements are (see “Element Classes” on page 16). The main difference is that each of an object’s properties has only one value, whereas an object may have many different elements of a single class.
Properties of an object are distinguished from each other by their unique labels. For example, the script that follows sets the Position property of the file MyFile, causing the icon for that file to move to the specified position.

set position of file "MyFile" to {29, 235}
end tell
The file in this example must be located on the desktop. A file can have only one Position property, distinguished from the other properties of the file by its label, position.
The Properties section of an object class definition lists all the property labels defined for that object and describes how to use them, including the class used for each property’s value and whether or not the property can be modified. Some objects inherit some or all their properties from other related objects. For example, the definition for File that begins on page 61 lists several properties that are inherited from the object class Item and several that are defined specifically for class File.
IMPORTANT
A property name has no plural form, even if you use it to refer to more than one property.
This script gets a list of the names of the files at the top level of the startup disk:
tell application "Finder"
name of files in startup disk
end tell
If you replace name with names, the script won’t compile.
Element Classes 2
Elements are objects contained by an object. For example, a folder can contain files and other folders. The element classes listed in an object class definition show what kinds of elements objects of that class can contain. An object can contain many elements or none, and the number of elements of a particular class may change over time.
A file can be an element of other Finder objects in which files can be stored, such as folders, disks, or the desktop; so File is listed as one of their element classes. The definition for object class File that begins on page 61 indicates that a file can’t contain any other elements.
16 Using Object Class Denitions
CHAPTER 2
Finder Objects
Commands Handled 2
Objects that belong to the same class can respond to the same commands. Object class definitions list the commands to which all objects of that class respond.
For example, the definition for File that begins on page 61 indicates that you can use any of these commands to perform actions on a file: Clean Up, Copy, Count, Data Size, Delete, Duplicate, Exists, Get, Make, Move, Open, Print, Put Away, Reveal, Select, Sort, Update.
Default Value Class Returned 2
In most scriptable applications, each object has a value that you can obtain simply by referring to the object in a script. For example, the value of a paragraph object in a word-processing application is a string that includes style and font information.
Unlike other scriptable applications, the Finder can control only the representa­tion of its objects within windows and the properties it defines for them; it can’t retrieve or alter text in a text file, for example. Therefore, the value returned for most Finder objects is a reference to the object, not the object’s data.
For example, this script returns a reference to the file MyFile, not the contents of the file:
tell application "Finder"
get file "MyFile" of startup disk
end tell
--result: file "MyFile" of startup disk of application "Finder"
Examples 2
Each object class definition in this book include one or more short examples demonstrating how to use the object name in a script. The first example for the File command definition that begins on page 61 is a script that returns a list of references to files whose modification dates are greater than a specified date, and the second example is a script that copies an icon to a group of files.
Using Object Class Denitions 17
CHAPTER 2
Finder Objects
The Finder Application Object 0
The Finder application object belongs to the object class Application. As is usually the case with scriptable applications, the application object functions as the outermost container for most of the objects the Finder defines.
To send commands to the Finder, use a Tell statement addressed to the Finder:
tell application "Finder"
open startup disk
end tell
––result: startup disk of application "Finder"
The result shown appears in the Script Editor’s Result window. The statement
startup disk of application "Finder"
is a complete reference to the startup disk. The Finder application itself is the startup disk’s container. Disks, folders, and files are examples of objects that can be elements of the Finder application. Folders and files can in turn be elements of disks or of folders within disks.
You can identify nested Finder objects in a variety of ways. For example, if the startup disk is named My World, these statements all identify the same object:
folder "My Folder" of startup disk of application "Finder" folder "My Folder" of disk "My World" of application "Finder" item "My Folder" of container "My World" of application "Finder" container "My World:My Folder" of application "Finder"
When recording is turned on, the Finder always records references the same way. Although the Finder can interpret the four statements in the previous example correctly, it records the reference as shown in the first statement.
18 The Finder Application Object
CHAPTER 2
Finder Objects
To obtain a standard reference to an element of the Finder while you’re writing a script, follow these steps:
1. Select the object.
2. Choose Copy from the Edit menu.
3. Activate the Script Editor application.
4. Click at the point in your script where you want to paste the reference.
5. Choose Paste Reference from the Edit menu.
Windows are also elements of the Finder application. You can address a Tell statement to a Finder window anywhere in a script:
tell front window of application "Finder"
close
end tell
Because window is a standard AppleScript term, AppleScript can interpret this script correctly. However, when it compiles a script, AppleScript doesn’t look up the Finder’s terminology definitions until after it has compiled the first line of the first Tell statement that addresses the Finder. Therefore, a script that consists of a Tell statement addressed to any other Finder object won’t compile:
tell startup disk of application "Finder"
open
end tell
To address a Tell statement to a Finder object other than a window, enclose it within another Tell Statement, like this:
tell application "Finder"
tell startup disk
open
end tell
end tell
The Finder Application Object 19
CHAPTER 2
Finder Objects
Properties and Elements of the Finder 2
The Finder application, like most other Finder objects, has many properties you can refer to in scripts. Some of these properties provide a shorthand method of referring to certain specialized objects.
For example, although the Finder application can contain any number of folders, only one Apple Menu Items folder can be located in the active System Folder for a given Macintosh computer. The Apple Menu Items folder can be described in a script as either an element of the System Folder or a property of the Finder application.
This script identifies the Apple Menu Items folder as an object contained by the System Folder:
tell application "Finder"
open folder "Apple Menu Items" of ¬
folder "System Folder" of startup disk
end tell
This script identifies the Apple Menu Items folder as a property of the Finder application:
tell application "Finder"
open apple menu items folder
end tell
Other specialized containers, such as the startup disk, the System Folder, the Startup Items folder, and the Extensions folder, are also defined as Finder properties.
Note
You can use the Path To scripting addition command to obtain references to some of the objects that can be identified as properties of the Finder. However, Path To use its own constants for these references and returns a pathname as an AppleScript reference of the form alias "Disk:Folder1:Folder2:...:Filename".
The desktop is another container you can identify as a property of the Finder. Any items contained by the desktop—that is, items that are “loose” on the
20 The Finder Application Object
CHAPTER 2
Finder Objects
working area of your screen and not contained by a folder, disk, or other object—can be considered elements of either the desktop or of the Finder application object, as shown in the following examples.
This script requests a list of the items contained by the desktop:
tell application "Finder"
items of desktop
end tell
--result: {trash of application "Finder", disk "Applications" of application "Finder", disk "Storage" of application "Finder", startup disk of application "Finder"}
If you request the items of the Finder application, you get a similar list:
tell application "Finder"
items
end tell
--result: {trash of application "Finder", disk "Applications" of application "Finder", disk "Storage" of application "Finder", startup disk of application "Finder", desktop of application "Finder"}
The only difference is that the second list includes a reference to the desktop itself, which is also an item contained by the Finder application.
Finally, if you request the contents of the Finder application, you get a list that includes references to windows and to currently running processes as well as to the Finder’s items:
tell application "Finder"
contents
end tell
--result: {trash of application "Finder", disk "Applications" of application "Finder", disk "Storage" of application "Finder", startup disk of application "Finder",
The Finder Application Object 21
CHAPTER 2
Finder Objects
window of startup disk of application "Finder", content space of desktop of application "Finder", desktop of application "Finder", application "Scriptable Text Editor", application "Script Editor"}
For complete lists of the Finder application object’s properties and element classes, see the definition for the Application object class, which begins on page 31.
References to Finder Windows 2
One of the Finder elements you can refer to in scripts is a content space, which can be any kind of window or the desktop. If you request all the content spaces, the Finder returns a list of references to all kinds of windows (container windows, information windows, sharing windows, and status windows) and the desktop:
tell application "Finder"
content spaces
end tell
--result: {information window of startup disk of application "Finder", window of folder "Projects" of startup disk of application "Finder", window of startup disk of application "Finder", window of disk "Applications" of application "Finder", content space of desktop of application "Finder"}
The result shown in the preceding example includes one information window, three container windows, and the desktop content space. An information window is the window that opens when you select an object’s icon in the Finder and choose Get Info from the File command. Containers are objects that can hold other objects, such as suitcases, folders, disks, and the desktop, and a container window is a window that belongs to a container. The only exception is the desktop window. Even though the desktop is a container, the desktop
22 The Finder Application Object
CHAPTER 2
Finder Objects
content space is a special case and the Finder doesn’t consider it a member of class Window (although you can refer to window of desktop in a script).
The desktop “window” and the desktop are actually the same object, whereas all other windows are distinct from the objects they belong to and may have different properties. For example, the Position property of a disk is different from the Position property of the disk’s window.
The desktop doesn’t have most of the characteristics of windows, so you can’t refer to properties such as Bounds, Position, and so on. If you are performing operations on Finder windows that involve these properties, you may want to get a list of windows that doesn’t include the desktop. Therefore, the Finder doesn’t include the desktop when you request a list of windows:
tell application "Finder"
windows
end tell
--result: {information window of startup disk of application "Finder", window of folder "Projects" of startup disk of application "Finder", window of startup disk of application "Finder", window of disk "Applications" of application "Finder"}
The list of window references returned doesn’t include the desktop, but it does include information windows and any other windows that are open. If you want to get a list restricted to windows that belong to containers, request a list of container windows:
tell application "Finder"
container windows
end tell
--result: {window of folder "Projects" of startup disk of application "Finder", window of startup disk of application "Finder", window of disk "Applications" of application "Finder"}
The Finder Application Object 23
CHAPTER 2
Finder Objects
You can refer to windows by name, by number, or as the window property of the object to which they belong. For example, these statements are equivalent:
window "My Folder" window of folder "My Folder" of startup disk
These statements are also equivalent:
window 1 front window
The Finder’s front window isn’t necessarily the active content space, which can be the desktop as well as a window. To get a reference to the active content space, use this statement:
content space 1
References Returned for the Insertion Location property 2
The Finder’s Insertion Location property returns a reference to the object to which new information can currently be added. For example, if the New Folder command in the File menu is active, the insertion location is a reference to the container in whose content space the new untitled folder appears when you choose New Folder. This container can be a folder, a disk, or the desktop:
tell application "Finder"
insertion location
end tell
--result: desktop of application "Finder"
If the active content space is a sharing window or an information window, the insertion location is a reference to the container to which the window belongs.
24 The Finder Application Object
CHAPTER 2
Finder Objects
References Returned for a Point 2
To get a reference to the content space that lies under a particular point on the desktop, run a script like this:
tell application "Finder"
content space {100, 100}
end tell
--result: window of folder "Projects" of startup disk of application "Finder"
The pair of integers in braces identifies the point in which you’re interested relative to the entire screen (including the menu bar), and the result contains a reference either to a window or to the desktop. It is usually easiest to use the term Content Space to obtain this kind of reference, because the script returns a reference even if the point is located in the desktop window.
You can also specify more restricted window classes, such as Window, Container Window, Information Window, and so on, as shown in the next example.
tell application "Finder"
container window {100, 100}
end tell
The script in this example returns a reference only if a container window contains the specified point. If the specified point is located in some other kind of content space, such as the desktop or an information window, the script returns an error.
You can use similar methods to find out whether an item or other object lies under a particular point. For example, this script returns a reference to an item if the item’s bounds enclose the specified point:
tell application "Finder"
item {100, 100}
end tell

tell application "Finder"
every accessory process
end tell
--result: {application "Alarm Clock”, application "Calculator", application "Notepad"}
Accessory Suitcase 2
An object of class Accessory Suitcase is a desk accessory suitcase.
PROPERTIES
An accessory suitcase has all the properties defined for object class Container on page 43: Completely Expanded, Container Window, Entire Contents, Expandable, Expanded, Previous List View, Selection, and View.
Like any other container, an accessory suitcase also has all the properties defined for object class Item on page 73: Bounds, Comment, Container, Content Space, Creation Date, Disk, Folder, Icon, ID, Information Window, Kind, Label Index, Modification Date, Name, Physical Size, Position, Selected, Size, and Window.
Object Class Denitions 27
CHAPTER 2
Finder Objects
ELEMENT CLASSES
The only elements that an accessory suitcase can contain are objects of class Item (see page 73 for the definition of Item). Items can be identified within an accessory suitcase by name or by number.
COMMANDS HANDLED
Clean Up, Copy, Count, Data Size, Delete, Duplicate, Exists, Get, Make, Move, Open, Put Away, Reveal, Select, Set, Sort, Update
DEFAULT VALUE CLASS RETURNED
Reference to a suitcase or, if you use the plural form accessory suitcases, a list of references.
EXAMPLE
This script returns a list of references to the accessory suitcases at the top level of the startup disk:
tell application "Finder"
accessory suitcases of startup disk
end tell
--result: {suitcase "DAs" of startup disk of application "Finder", suitcase "More DAs" of startup disk of application "Finder"}
Alias File 2
A object of class Alias File is an alias—that is, a file that represents another file or volume. Icons for alias files have italicized names.
PROPERTIES
An alias file has all the properties defined for object class File on page 61: Creator Type, File Type, Locked, Product Version, Stationery, and Version.
28 Object Class Denitions
CHAPTER 2
Finder Objects
Like any other file, an alias file also has all the properties defined for object class Item on page 73: Bounds, Comment, Container, Content Space, Creation Date, Disk, Folder, Icon, ID, Information Window, Kind, Label Index, Modifica­tion Date, Name, Physical Size, Position, Selected, Size, and Window.
Unlike other files, an alias file also has this property:
original item
ELEMENT CLASSES
None
COMMANDS HANDLED
Clean Up, Copy, Count, Data Size, Delete, Duplicate, Eject, Empty, Exists, Get, Make, Move, Open, Print, Put Away, Reveal, Select, Sort, Update
A reference to the original item associated with the alias file.
Class: Reference Modifiable: No
DEFAULT VALUE CLASS RETURNED
Reference to a file or, if you use the plural form alias files, a list of references.
EXAMPLE
If you run this script from the Script Editor, it reveals the original items for any alias files that are currently selected:
tell application "Finder"
get selection repeat with moose in result
if original item of moose exists then
reveal original item of moose
end if
end repeat
end tell
Object Class Denitions 29
NOTES
CHAPTER 2
Finder Objects
The Get statement in this script returns a list of references to the selected items. The Repeat statement tests the Original Item property for each selected alias file. If the property’s value is a valid reference, the If statement asks the Finder to reveal the original item.
For an example of a script application that performs a similar task, see the definition of the Reveal command on page 131. For examples of scripts that create alias files, see the definition of the Make command beginning on page 121.
A reference to an object of class Alias File in a Tell statement addressed to the Finder is different from an AppleScript reference that uses an alias. You can use an AppleScript alias reference like this anywhere in a script to identify a file:
alias "Disk:Folder1:Folder2:...:Filename"
When you compile the script (for example, by clicking the Check Syntax button in the Script Editor), AppleScript creates an alias record that identifies the file even after you move the file from its original location—as long as you don’t recompile the script.
Like an alias record, an alias file identifies another file or folder even after the original has been moved. However, a reference to an alias file is just like any other Finder reference: it must provide a complete description of the alias file’s location in a form similar to this:
tell application "Finder"
alias file "Filename" [ of container "ContainerX" ]... ¬
of container "Container1" [ of disk "Disk" ]
end tell
If you move the alias file, the reference won’t be accurate any longer. Also, if you attempt to use a Finder reference to an alias file outside of a Tell statement addressed to the Finder, the script won’t run.
30 Object Class Denitions
CHAPTER 2
Finder Objects
Application 2
An object of class Application is the Finder application itself, the outermost container for most Finder objects.
Because of its role as the application that controls the Macintosh desktop, the Finder defines its own application object differently from the way most other applications define their application objects. For an introduction to the role of the application object in scripts that control the Finder, see “The Finder Application Object,” which begins on page 18.

Elements of any of these classes can be identified by name or by number. With the exception of the desktop and window objects such as container windows and information windows, an element of the Finder can also be identified by an AppleScript alias record—that is, a representation of an object, much like an alias icon on the desktop, that identifies the object. For example, both these statements refer to the same file:
alias "Hard Disk:MyFile" file "MyFile" of disk "Hard Disk"
In most cases the Finder can accept a reference like the first example, but you can’t use a Finder reference like the second example outside of a Tell statement addressed to the Finder. This book describes how to use Finder references. For information about AppleScript references to alias records, files, applications, machines, and zones, see the AppleScript Language Guide.
Objects of class Application File, Disk, and Folder can also be identified by ID. The ID in each case consists of the application file’s creator type (as a string), the disk’s ID, and the folder’s folder ID, respectively. For example, this state­ment identifies the startup disk:
disk ID -1
-—result: startup disk of application "Finder"
Object Class Denitions 35
CHAPTER 2
Finder Objects
This statement identifies a folder:
folder ID 918 of startup disk
-—result: folder "My Folder" of startup disk of application "Finder"
This statement identifies the TeachText application:
application file id "ttxt"
-—result: file "TeachText 7.1" of startup disk of application "Finder"
You can identify the frontmost window that lies under a particular point on the desktop by running a script like this:
tell application "Finder"
content space {100,100}
end tell
--result: window of folder "Projects" of startup disk of application "Finder"
The pair of integers in braces in the preceding example identifies the point in which you’re interested, and the result contains a reference to the window that contains that point. It is usually easiest to use the term Content Space to obtain this kind of reference, because the script returns a reference even if the point is located on the desktop or in some specialized window such as an Information Window.
You can also specify more restricted window classes, such as Window, Container Window, Information Window, and so on. For example, if you request a reference to a container window for a point that’s located in some other kind of window, the Finder returns an error.

Although Startup Disk and Trash are properties of the desktop object, you can also refer to them as if they were properties of the Finder. Thus, the Finder interprets both of these statements are references to whatever disk is currently the startup disk:
startup disk startup disk of desktop

CHAPTER 2
Finder Objects
Similarly, the Finder interprets both of these statements as a reference to the Trash:
trash trash of desktop
Application File 2
An object of class Application File is an application’s file on a disk. References to application files must always include a complete description of the file’s container. Such references are different from standard AppleScript references to application objects, which don’t always require a complete pathname.
PROPERTIES
An application file has all the properties defined for object class File on page 61: Creator Type, File Type, Locked, Product Version, Stationery, and Version.
Like any other file, an application file also has all the properties defined for object class Item on page 73: Bounds, Comment, Container, Content Space, Creation Date, Disk, Folder, Icon, ID, Information Window, Kind, Label Index, Modification Date, Name, Physical Size, Position, Selected, Size, and Window.
Unlike other files, an application file also has these properties:
minimum partition size
An integer indicating the minimum amount of memory, in bytes, that the application requires to run. This value is equivalent to the value in the box labeled “Minimum size” under “Memory Requirements” in the application file’s information window (see “Notes”).
Class: Integer Modifiable: Yes
partition size
An integer indicating the amount of memory, in bytes, that the application is launched with if a block of this size is available. This value is equivalent to the value in the box labeled “Preferred size” under “Memory Requirements” in the application file’s information window (see “Notes” on page 40).
Class: Integer Modifiable: Yes

level event aware (true) or not (false)—that is, whether it can respond to the Open, Run, Print, and Quit commands.
Class: Boolean Modifiable: No
An integer indicating the amount of memory, in bytes, suggested for running the application. This value is equivalent to the value in the box labeled “Suggested size” under “Memory Require­ments” in the application file’s information window.
Class: Integer Modifiable: No
DEFAULT VALUE CLASS RETURNED
A reference to a file or, if you use the plural form application files, a list of references.
EXAMPLES
The script that follows checks the Scriptable Text Editor’s partition size before opening the application. If the amount of memory available is greater than the partition size, the script opens the application. If the amount of memory available is less than the partition size, the script displays a dialog box warning the user that the Scriptable Text Editor prefers more memory. This might be useful if a script performs actions requiring more memory than an applica­tion’s minimum partition size permits.

NOTES
The Minimum Partition Size, Partition Size, and Suggested Partition Size are all given in bytes. These values are shown in information windows in kilobytes (K, where 1K = 1024 bytes).
The value of the Partition Size property must be at least as high as the value of the Minimum Partition Size property. If you set the Minimum Partition Size to a value higher than the value of the Partition Size, the Finder also adjusts the Partition Size to match the new Minimum Partition Size. Similarly, if you set the Partition Size to a value lower than the value of the Minimum Partition Size, the Finder also adjusts the Minimum Partition Size to match the new Partition Size.
For example, suppose that the Partition Size and the Minimum Partition Size of the Scriptable Text Editor are both set to 384K. Running this script sets the

Container 2
An object of class Container is any Finder container, such as a folder, a disk, or the Trash.
PROPERTIES
A container has all the properties defined for object class object class Item on page 73: Bounds, Comment, Container, Content Space, Creation Date, Disk, Folder, Icon, ID, Information Window, Kind, Label Index, Modification Date, Name, Physical Size, Position, Selected, Size, and Window.
Unlike other items, a container also has these properties:
completely expanded
A Boolean value that indicates whether a container and any folders it contains are completed expanded in list view (true) or not (false). For a container to be completely expanded, the window that contains the container must be open in list view (that is, any item other than “by Small Icon” or “by Icon” is selected in the Views menu for the window), the container and all nested folders within the it must be fully expanded with that same list view, and the container’s own window must be closed. Before you can set this property, the window that contains the container must already be open in a list view.
Class: Boolean Modifiable: Yes
container window
A reference to the container’s window.
Class: Modifiable: No
entire contents
A list of references to the entire contents of the container, including the contents of any other containers within the container.
Class: List of references Modifiable: No
Object Class Denitions 43
CHAPTER 2
Finder Objects
expandable A Boolean value that indicates whether the container can
be opened within its container in outline view (true) or not (false).
Class: Boolean Modifiable: No
expanded A Boolean value that indicates whether the item is open in
outline view (true) or not (false).
Class: Boolean Modifiable: Yes
previous list view
An integer between 2 and 8 or one of the corresponding constants
name, modification date, size, kind, comment, label index, or version. If the View property of the container is
currently one of these list views, the value of this property is the current list view. If the View property is small icon or icon, the value of this property is the last list view selected. If no list view has been selected since the container was first opened, the value of this property is name. You can’t get or set this property unless the container is open, and the value of the property isn’t retained after the container has been closed.
Class: Integer Modifiable: No
selection A list of references to the container elements that are currently
selected. The elements in the selection are those that would be cut by a Cut command or copied by a Copy command. If no elements are selected, the value of the Selection property is an empty list.
Class: List of references Modifiable: Yes
view An integer between 0 and 8 or one of the corresponding constants
small icon, icon, name, modification date, size, kind, comment, label index, or version, indicating the current
selection in the View menu for the container’s window. You can’t get or set this property unless the container is open.

EXAMPLES
CHAPTER 2
Finder Objects
The first example opens all the containers on the desktop except for the Trash.
tell application "Finder"
open (containers in desktop whose name is not "Trash")
end tell
The next example, if saved as a script application, toggles the value of the Completely Expanded property of all containers at the top level of the front window: that is, it alternately expands all the containers and their nested containers or collapses them. The window in which the script application is located must be open in list view for the script to work on the window’s contents.
property expan : false
tell application "Finder"
if expan = false then
set completely expanded of containers in ¬
container of front window to true
set expan to true
else
set completely expanded of containers in ¬
container of front window to false
set expan to false
end if
end tell
The script begins by declaring the value of the expan property to be false. This property is a Boolean value that changes after the script is run. The script sets expan to true whenever it sets the Completely Expanded property of the front window’s containers to true, or to false whenever it sets their Completely Expanded property to false.
The value of the property container of front window is a reference to the container to which the window belongs. This script must specify the Container property of the window, rather than the window itself, or it may not work consistently. A window’s container always has a fixed number of elements until new elements are added or deleted, whereas a window open in list view has a variable number of elements depending on which folders are expanded.

An integer between 2 and 8 or one of the corresponding constants
name, modification date, size, kind, comment, label index, or version. If the View property of the container
window is currently one of these list views, the value of this property is the current list view. If the View property is small icon or icon, the value of this property is the last list view selected. If no list view has been selected since the container window was first opened, the value of this property is name.

ELEMENT CLASSES
The elements of a container window include all the items currently displayed inside the window. When folders in a window whose View property is name, date, size, or kind are expanded in outline view, the elements of the expanded folder become elements of the container window in which the folder is located.
You can’t get or set this property unless the container window is open, and the value of the property isn’t retained after the container window has been closed.
Class: Integer Modifiable: No
Class: Reference or list of references Modifiable: No

end repeat
end tell
Object Class Denitions 49
CHAPTER 2
Finder Objects
The phrase count of container windows at the beginning of the Repeat loop requests that the Finder count all the container windows. Windows that aren’t container windows, such as information windows, are ignored. The Finder returns an integer, which the Repeat statement uses as the number of times to repeat.
The If statement within the Repeat statement resets the bounds of each successive container window so that it is shifted down and to the right from the previously tiled window. After the View for each container window is set, the last statement within the Repeat statement sends an Open command to that window so that it overlaps the previously tiled window.
Content Space 2
An object of class Content Space can be any Finder content space, including a container window, the desktop, an information window, a sharing window, a status window, or a window.

DEFAULT VALUE CLASS RETURNED
A reference to a file, folder, disk, the Trash, or the desktop or, if you use the plural form items, a list of references.
EXAMPLES
The script that follows moves a group of items that start with an at (@) symbol back and forth between the Apple Menu Items folder and a folder at the top level of the startup disk called Apple Menu Extras.
To work correctly, this script must be stored as a script application at the top level of the startup disk; the startup disk must also contain a folder called Apple Menu Extras to store the items you want to move in and out of the Apple Menu Items folder; and the names of the items in the Apple Menu Items folder must all begin with an @ symbol. It is also important, as with any script, to have some free memory available in addition to the memory used by any currently running processes—preferably several hundred kilobytes.

startup disk) at apple menu items folder ¬ with properties {name:" Add Extras"}
end if
if Extras is false then
move contents of folder "Apple Menu Extras" of startup disk to ¬
apple menu items folder
set the name of item " Add Extras" in apple menu items folder ¬
to " Remove Extras"
set Extras to true

whose name begins with "@") to ¬ folder "Apple Menu Extras" of startup disk
set the name of item " Remove Extras" in ¬
apple menu items folder to " Add Extras"
set Extras to false
end if
end tell
The script begins by declaring the value of the Extras property to be false. This value may change after the script is run.
If the script hasn’t been run before, the first If statement in the script creates an alias file of the script application in the Apple Menu Items folder with the name Add Extras. This alias file appears in the Apple menu along with all the other

If the value of Extras is false, the first part of the second If statement moves the contents of the Apple Menu Extras folder into the Apple Menu Items folder, changes the name of the alias file to Remove Extras, and sets the value of Extras to true.
If the value of Extras is true, the second part of the second If statement moves all items in the Apple Menu Items folder that begin with an @ symbol into the Apple Menu Extras folder, changes the name of the alias file to Add Extras, and sets the value of Extras to false.
