While you should first review the memory articles at http://www.aumha.org/articles.htm the reason some pagefile will be used even if there is RAM to spare, the truth is that an idle program may as well be tossed there so the RAM can be better used as disk cache or "other".

I need a few things explained to me.... isn't the page file a space on your hard drive that your computer uses as if it were RAM?? If this is so, why is my computer using 300 MB of my page file if I still have over 600 megs of unused RAM?
