Tips on installing Windows programs...

Always install a new Windows program to a separate 
directory. Most set up or install programs will advise 
you where they intend to copy their program files. This 
will NOT insure that other files won't be placed in the 
WINDOWS or WINDOWS\SYSTEM directories but it will make 
it easier to clear out all their related files when and 
if the time comes.

With existing Windows programs on your hard disk you 
could print out a listing of the directories of each 
diskette on which the original program was purchased. 
This would give you a list of files to hunt down and 
delete to clear out non-essential files.

A word of caution first, a file that came with one 
program could also have been on another program's 
diskettes and may be used by more than one program. Be 
attentive when trying this method and save these files 
separately for a period of time, until you have tried 
any other programs that may those use the same files.

Some programs now come with a readme or other text file 
which lists all files that are associated with that 
particular application. This is important to look for 
and can save hours of searching and headache.
