Indicates which files to use or not to use with keyword expansion. Used in the SRCSAFE.INI file.
Keyword_Masks = masks
Indicates that all .C and .H files except for SS.C should be keyword expanded:
Keyword_Masks = *.C, *.H, !SS.C
By default, VSS does not scan files for keyword expansion when it performs a Check In or Add Files command. Set this variable to indicate which VSS files should be keyword expanded, noting that the Add File and Check In commands may be slower for these files.
You can also set this variable in the SRCSAFE.INI file with the Expand Keywords In Files Of Type option, which is accessed by clicking Options on the Tools menu, then selecting the General tab.
