There is a relationship between the presence of these files, the way they affect memory (RAM), and their effect on other running applications. Therefore, we recommend that you make a habit of deleting the contents of the Temp folder on a weekly basis. You may fear deleting some files...their names may sound cryptic, important, or even critical, and some files may refuse (!) to be deleted. Anything remaining in the C:\Windows\Temp folder after a fresh reboot is absolutely unnecessary and a perfect candidate for deletion. And a file that won't be deleted the first time WILL be deleted after a reboot of your computer.
