|CCleaner deletes garbage & garbage only. When it was 1st released it was called "Crap Cleaner" but I guess that name offended some people so it was changed to CCleaner. When you 1st open it, there's a list of the types of files it deletes in the left column. You'll find that there's nothing there that's critical, it's all "crap". It's safe to delete everything it finds.|
Out of curiousity, after you ran the analysis, how much did it say it would remove?
