I use ccleaner and ATF-cleaner by Tribune. I also monthly perform a cleanboot process to keep the machine in good working order along with weekly maintenance programs. I rarely have trouble with this system and I am in better working order than many win xp users out there. I check TEMP file every two(2) weeks at least. I try to keep this machine in pristine shape. I note that many of the AV vendors are using this TEMP file and that is ok as long as I do not remove something that is needed. As far as worry about the file, when I first learned about this many windows machines were slowing down to a crawl and people were abandoning them because of autostart/runs and junk hidden in files like the temp that were hang-on spyware etc. picked up in the early 2k era. >:( :wink:
