VSS provides two initialization files that contain settings you can use to customize your VSS environment:
Each user has an SS.INI file that can be edited.
Important Only the VSS administrator should edit SRCSAFE.INI.
Manually editing the initialization files is not recommended, unless you are very familiar with VSS initialization variables and their behavior. Instead, you should set most initialization variables directly in VSS in the Options dialog box on the Tools menu. You can set the SRCSAFE.INI variables in the VSS Administrator Options dialog box.
For information on how to customize the SS.INI and SRCSAFE.INI files, refer to:
