If you have ever reformatted your computer or uninstalled and
application and need it back, but can’t find the install CD, a simple
way to do this is by keeping a backup copy in a CD binder. Considering
recordable CD’s and DVD’s are dirt cheap and you can pick up a 128
count CD binder for about $12, why not burn a copy of your application
CD’s, write the serial numbers on the CD and store them away? It only
takes about 10 minutes per CD to make a copy and can really save you a
lot of hassle if you ever lose, scratch, break, or accidentally feed
your original CD to the dog.
