Hello good people of Ars, I have an older PC I built that has a 100GB SSD for the operating system and associated programs. It is currently at capacity. I've exhausted all other feasible options to ...

Virtual memory, also known as a Page file, adds to the physical RAM by using disk space. However, moving the page file to a secondary SSD can help free up space if you run out of space on the primary.

I'm running WinXP with three hard drives: two of them in RAID 0 (with all my files on them) and a third one that I use as a backup (in case the RAID fails; it has nothing except a backup file on it).
