Hi sallyr. Can you give us a link to your earlier posting, or summarise the problem so far.
You should be able to empty your windows/temp folder with no problems. The usual reason for so many files being there is that many program installers don't clear up after the installation is finished. You can always delete the files but not empty the recycle bin for a few days, or move the files to a temporary folder that you create for the purpose before finally deleting them. That way, if you do get any problems, which is most unlikely, you can restore the files.
