As Kirk, Roy and Peter suggested (nay, commanded), use a versioning 
system, either CVS or Subversion for example (both are quite simple, 
Subversion has a 1 click installer for Windows boxes, and there is a 
small book/user manual with it so that you're not lost), they'll do what 
you need (keep the old versions around "just in case") and much more to 
boot. Spending a day or two learning about how the versioning system 
you'll have chosen work is an investment that you'll get back tenfold in 
no time, so don't get intimidated or scared.
