RCS or "revision control system" is an archive program for configuration files. It will store past versions of text files.

if you intend to modify your gamefiles, make mods and the like you should learn to use tools designed for exactly this problem which is known in the industry as 'configuration management'

With CVS (the big brother to RCS) you can label an entire set of config files as a 'version' and 'check out' that whole version. This permits you to modify multiple files involved in a mod, and tag them as a 'version' and later recover the configuration of that 'version' if you need to branch or bugfix an old mod without the chaos of multiple versions of text files.

I recommend using CYGWIN, which is available at cygwin.com.
