Sorry about that Piney, I seen that you pm'ed me, but my popup blocker has blocked it here at home but not here at work. It dont matter if you delete the folder or the file, after you reboot, the folder comes back with new files in it. It just one less step to take. And why to delete every once in awhile.... This is an unique technique for WinXP. We know that it is necessary to wash registry and TEMP files for Win9X/ME/2000 periodly. Prefetch is a new and very useful technique in Windows XP. However, after using XP some time, the prefetch folder can get full of rarely used or obsolete links which can slow down your computer noticeably. My suggestion is: open C(system drive):/windows/prefetch, delete all files (or at least those more than 3 weeks old), reboot. I recommended that you do this every month. I do this about once a week personally. It up to you if you want to delete the folder ot just the files them selves. Did this help you out?
