I'm trying to familiarize myself with the stuff that CCleaner cleans up. Could someone please tell me whether it is perfectly safe to remove the files listed under System temporary files? I have years' worth of these on my computer.
I also have the same question about office xp files. I looked at the file names and they were a mix of stuff relating to documents and folders I had recently added or changed, all with .LNK suffix.
I have an image backup in case anything goes wrong, but I still would like to know that I'm not doing anything inherently harmful.
