Hi, No problems,just wondering... The windows swap file works with a paging method right? The expanded memory system (EMS) works also with paging and is managed by emm386.exe Can it be said that the virtual memory,and thus the swap file,is also managed by emm386.exe? Or am i talking a lot of nonsense now? Who can help me out? Thankz... Roy

Expanded Memory is relevant only to DOS. Windows is able to use all memory beyond 1MB freely, but DOS has to be tricked into it. Expanded memory is one way DOS can be fooled into using memory beyond the 640KB system memory. DOS uses expanded memory only because it doesn’t realize that it has moved out of conventional memory. An expanded memory manager handles this deception by swapping 64KB chunks of information, called pages, into and out of reach of the DOS application. Virtual Memory uses the computer’s hard drive, which most of us think of just as a permanent storage device, for volatile storage (memory). If your computer has a 386 or better processor, along with Windows, it can use virtual memory to overcome RAM shortages. The computer just reserves a portion of the hard drive and writes information that would normally go into RAM into this space instead. This reserved area is called a swap file. The swap file does a good job of increasing the memory available to applications. It lets you do more with your computer without buying and installing additional RAM chips, but it does have its limitations. It isn’t as fast as ‘real’ RAM and you can’t use it on a drive that has been compressed (by Stacker or any other commercial drive compression utility). So, if you’re running short of drive space and memory, it’s time to add to one or the other.
