While running Disk Cleanup in Windows XP Home Edition, is it safe to delete Temporary Files? (not Temporary Internet Files). When I click on the heading "Temporary Files" in the Disk Cleanup dialogue box a message comes up saying: "You can safely delete temporary files that have not been modified in over a week". So how do I know if temporary files have not been modified in over a week in order to delete them safely? Advice on this matter would be very welcome as I would then gain an extra 220MB of useful space on a pathetically small 9.5GB (in total) disk drive. Any help would be much appreciated. Geoff.
