Folks: I am using Windows XP and am getting all kinds of messages about my temporary files. I tried Disk Cleanup but it doesn't work as it just hangs up when I try to run it. I tried going to "Search" and typed *.tmp and a bunch of files showed up. Is it OK if I went ahead and deleted all these files? Would I harm my computer in any way? Are there any .tmp files that XP needs that shouldn't be deleted at all? Thanks for any help.
