No "program" has been found that would alert you as to which files are safe to remove. But most can be researched on google.com
I have Windows 2000, lately it has been slowing down.
What program (s) could I use safely to delete unnecessary files from the hard drive? It has to be easy enough for a beginner to use, as I am new at computers.
I do clean my cache file often, I also do disk clean-up and disk defrag.
Would it be possible that using Norton for protection could be part of the problem?
