Visual Source Safe Term

Under normal operation in a stable environment, Microsoft Visual SourceSafe provides excellent storage and security for your current source data and past revisions.

Sharing and Branching

Use the Sharing and Branching features of Visual SourceSafe with discretion. Avoid Sharing or Branching across top-level projects because it complicates the process of archiving a project and restoring it into another database. Moreover, when you branch files and then delete them, the space is not recovered until all copies of the branched file in the database are destroyed.

Server Rights

All users must have create, modify, change/edit, and delete permissions for files in the Data folder and its subfolders in the directory tree. These permissions must also be applied to the share permissions. If a user receives the message "Unable to create user login file," that user does not have the proper permissions to the VSS database location.

Working Folders

To maintain file integrity, make sure that all users have their own working folders for all projects. When multiple users share a working folder, a file checked out by one user can be modified by anyone with access to that folder. Maintaining separate working folders ensures that users modify only files they have checked out themselves.
