This sensor reports the amount of disk space available for use as virtual memory. Potential virtual memory includes any free space on the disk, plus some portion of the space that has been already reserved for the Windows swap file.
Virtual memory enables your computer to run more applications simultaneously than the installed physical memory (RAM) would otherwise allow. When virtual memory gets low, computer performance deteriorates, running applications may not work properly, and you may not be able to start any new applications.
