Hi Stephen, Virtual memory is a way of storing information, such as data and program code that is larger than availible RAM. A"s it is "virtual," it is not physically present. Under some operating systems such as Windows NT and CE, each program (more precisely, process) gets certain amount of virtual memory. Under Windows NT and similar operating sywstems (2000, XP, Vista), each program is allowed to use whatever virtual space it needs. The overall virtual memory limit on these operating systems is 4 GB (for 32-bit systems. Under Windows CE, the limit is 32 MB (under CE 6.0 and above, the limit is 2 GB). Since it is "virtual," you won't see any reduction of free space on either KeySoft System Disk or on the Flash Disk. To learn more about how virtual memory works, go to: http://www.cs.umd.edu/class/spring2003/cmsc311/Notes/Memory/virtual.html My knowledge ends here. I think Jonathan, Alex Parks or any other people can explain more about this. Cheers, Joseph P.S.

Hi Folks, Just wondered, where does the nonphysical part of virtual memory come from? Is it taken from the flash or system "disk" or even somewhere else? Thanks and regards, Steve.
