Chapter 3 Sharing Files
Adding Shared Folders
Configuration from a Computer
1 In Advanced Settings, click File Sharing.
2 Click to the right of "Folder Setup".
3 Click Create Folder.

Notes:
• Names may contain up to 27 alphanumeric characters, hyphens (-), and underscores (_). Do not use a symbol
as the first character in a name.
20
• The description may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces. Do
not use a symbol or space as the first character.
• You may create up to 400 shared folders.
• The names of shared folders should not use characters from more than one language. For example, mixing
Japanese and Korean characters in names is not supported.
• If multi-byte characters are used in shared folder names, configure the client language to match the
characters in Management - Name/Time/Language.
Recycle Bin
To protect your data from accidental deletion, you may configure your LinkStation to use a recycle bin instead of
deleting files immediately. The recycle bin will only work with SMB connections.
Read-only Shares
By default, new shares are set with read & write access, but you may change the attribute to "Read Only" in
"Attribute". Read-only shares and HFS+ formatted USB hard drives will have "Read-only" added to the shared folder
description.
Hidden Shares
To hide a shared SMB folder, select "Hidden Share (SMB Only)" and click OK. To open a hidden folder, click Start Search programs and files and enter "\\LinkStation's name\Shared folder names$\" for the name. For example, if the
LinkStation name is "LSXXX001" and shared folder name is "share", enter "\\LSXXX001\share$\" to open it.
Note: AFP and FTP folders and USB drives cannot be hidden.
Configuration from a Mobile Device
1 In Settings, tap Folder Setup.
21
2 Tap Create Folder.

Note: Folder names may contain up to 27 alphanumeric characters and symbols. The description may contain
up to 75 alphanumeric characters.

Notes:
• Usernames may contain up to 128 characters, including hyphens (-), underscores (_), periods (.), !, #, &, @, $, *,
^, and %. Do not use a symbol as the first character.
• The user ID should be a number from 1000 to 1999. Each user ID should be unique. If this field is left blank, a
user ID is assigned automatically.
• When you log in to Settings as a registered user, you can see the LinkStation's name, IP address, workgroup,
and disk status, and modify the password.
• Do not duplicate user IDs, group IDs, usernames, or group names. Each should be distinct and unique.
• The description may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces. Do
not use a symbol or space as the first character.
• Passwords may contain up to 20 alphanumeric characters and the following characters: - _ @ ! # $ % & ' ( ) * + ,
. / ; < > = ? " [ ] ^ { } | ~. Do not use a symbol other than an underscore (_) as the first character.
• Use the same username and password for both Windows and the LinkStation or you may not be able to
access shared folders.
• If a user belongs to multiple groups, the most strict access restrictions will apply. For example, if a user is
added to a group with read and write access, and also to a read-only group, the user will effectively have
read-only access.
23
Configuration from a Mobile Device
1 In Settings, tap Users.
2 Tap Create User.

not use a symbol other than an underscore (_) as the first character.
• Group descriptions may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces.
Do not use a symbol or space as the first character.
• If the group ID field is left blank, a group ID is automatically assigned. Use numbers between 1000 and 1999
to set a group ID manually. Don't use duplicate group IDs.
• You may register up to 300 groups with the LinkStation.
• If you are logged in as a member of the general users group, you can only change your own password. If
you're logged in as an administrator, you can change any settings, including other users' passwords. If you are
logged in as a member of the power users group, you can create and edit shared folders, users, and groups.
Access Restrictions
You may restrict access to specific shared folders, including external USB drives.
Notes:
• Access restrictions can be set separately for each shared folder, but not for subfolders within the shared
folders.
• Configure access restrictions through Settings. Configuring access restrictions through Windows is not
supported and may cause unexpected behavior.
Local Users/Groups
1 In Advanced Settings, click File Sharing.
26
2 Click to the right of "Folder Setup".
3 Click the shared folder that you want to set access restrictions for.
4 Click Edit.
5 Enable "Access Restrictions".
6 Select the level of access for the user or group you added.
: Read and write access allowed : Read access allowed : Access prohibited
Notes:
• An example of access restrictions by user is shown in the screen. To apply access restrictions by group, click
the Local Groups tab and select group permissions.
• If both read-only and read & write permissions are given to a user, the user will have read-only access.
7 Click OK.
Notes
• The following characters are handled differently by Mac OS and Windows. Avoid using these characters when
sharing data between Mac OS and Windows:
• Windows does not support some characters that Mac OS and the LinkStation allow. If you create a filename on
a Mac with any of the following characters, it will not display correctly on a Windows computer and you may
have to connect to the LinkStation via AFP in order to display or copy any of the following characters on a Mac
computer.
? [ ] / \ = + < > ; : " , | *
27
• Do not use any of the following words as a username or group name: root, bin, daemon, sys, adm, tty, disk, lp,
sync, shutdown, halt, operator, nobody, mail, news, uucp, ftp, kmem, utmp, shadow, users, nogroup, all, none,
hdusers, admin, guest, man, www, sshd, administrator, ftpuser, apache, mysql
• Do not use any of the following words as the name of a shared folder. These words are reserved for internal use
by the LinkStation: info, spool, lost+found, global, printers, homes, lp, authtest, ram, msdfs_root, mt-daapd,
usbdisk# (where # is a number, for example: usbdisk1)
• Don't use the following unsupported characters in shared folder names, workgroup names, or filenames:
• File and folder names may contain up to 255 single-byte characters.
• Configure hidden and read-only file attributes in Settings. Configuring them from within Windows is not
supported and may cause unexpected behavior.
• Folder and workgroup names whose names contain non-Roman characters may not be displayed correctly.
• If shared folders are accessed from a Macintosh, information files for the Macintosh may be generated
automatically. Do not delete these files. If they are deleted using Windows, this may prevent further access from
a Macintosh.
• The LinkStation belongs to the default zone in AppleShare Server; the zone cannot be specified.
• When files are copied to the LinkStation or to a USB drive connected to the LinkStation, file information such as
date created, date modified, and other date information may be updated or changed.
• Hard drive capacity is shown in Settings in actual gigabytes. The Properties window in Windows may show GiB
instead, which will be a smaller number.
• If any settings are changed during a file transfer, the transfer process may abort.
• File copying to the LinkStation is protected by a journaling file system. If the Ethernet cable is disconnected or a
power outage occurs while copying data, the following may occur:
- Preset data such as the LinkStation name, users, and groups may be erased.
- An incomplete file may be copied and the file can no longer be deleted. If this happens, restart the LinkStation,
delete the file, and perform the copy operation again.
• After a drive is formatted, the "% Used" and "Amount Used" in Settings will not be 0. This is because some drive
space is used for the system area.
Active Directory
If an Active Directory environment, the LinkStation uses account information from the Active Directory domain
controller to set access restrictions for LinkStation's shared folders. There is no need to perform individual account
management for the LinkStation. If multiple LinkStations are installed on the network, the account information is
centrally managed in Active Directory, greatly reducing the operations required for installation and management.
Notes:
• The LinkStation supports a domain environment with a maximum 1000 users and 1000 groups. 10,000 users
and 10,000 groups can be downloaded from the domain controller but are not supported.
• If usernames or group names from Active Directory include multi-byte characters, you will not be able to
configure access restrictions for them.
