Before you run tests for the first time, do the following:
1. Understand where your test files are stored on the instrument.
2. Map my TekExpress folder as X: (X drive) on all instruments used in test setup running Microsoft Windows Operating System.
The My TekExpress folder has the shared name format <domain><user ID>My TekExpress. Or, if the instrument
is not connected to a domain, then the shared name format is <instrument name><user ID>My TekExpress. This
shared folder is used to save the test session files and is used during any other file transfer operations.
Note: If the X: drive is mapped to any other shared folder, the application will display a warning message asking you to
disconnect the X: drive manually
3. Make sure that the My TekExpress folder has read and write access and that the contents are not set to be encrypted:
a. Right-click the My T
