Visual source safe
Visual source safe is used to store our project files. It is client server tool.
But importance of VSS doesnt lie only on it main importance is multiple people can work on same project using VSS.
Load the project in VSSsuppose there are 2 people working on same solution person A and person B
If B had worked on File1 so if he is working on VSS he has to checkout the file first make his changes and checkin the file.
If A opens the same File1 he can see all the changes in File1 made by B but before that he has to click on File1 and Get latest version of File1 else he will not be able to see the changes made by B.
Now If A want to work on same File1 again A has to checkout the file and work and checkin again.
suppose B is in Checkout mode A cant checkout it.
Two persons cannot checkout the file and work on it simultaneously.
This is the importance of VSS.
Visual SourceSafe (VSS) is a client/server application which acts as a storage system for files. A file stored in a VSS server is not available via the standard file system, instead, it must be accessed through the VSS client tools - the VSS windows client, the VSS command-line tool, or else some application which integrates with or emulates these client tools.
