SYMPTOMS
While doing a GET or VIEW from the Show History dialog, a Check In of a large file, or a Difference on a large file, the user gets the following message:

"Invalid DOS path : "



CAUSE
The Temp_Path setting in the SRCSAFE.INI file is set to an invalid directory.



RESOLUTION
Edit the SRCSAFE.INI file and change the Temp_Path setting to an existing directory.

If Temp_Path is set to a network drive make sure that the network connection is stable.



STATUS
This behavior is by design.



MORE INFORMATION
The SRCSAFE.INI file has an initialization variable called Temp_Path. This tells Visual SourceSafe where to put its temporary files. If Temp-Path is set to a non-existent location, an error will occur when Visual SourceSafe attempts to access the non-existent location.

Visual SourceSafe will use a temporary directory when any one of the following actions is performed:


 * 1) Doing a GET of an older version of a file from the Show History dialog that it can't fit into memory. This is more likely to happen with binary files.
 * 2) Doing a VIEW of an older version of a file from the Show History dialog.
 * 3) Doing a Check In of a large file that it can't fit into memory. This is more likely to happen with binary files.
 * 4) Doing a Difference on a large file that it can't fit into memory. This is more likely to happen with binary files.

If the Temp_Path in the SRCSAFE.INI file is invalid, it may corrupt the file when any of the previously-mentioned actions are performed. By default, Temp_Path is set to a directory called "temp" that is created by the server installation. Therefore, this situation should only arise if a user has edited the SRCSAFE.INI file.
