Hi,
Virtual Memory is a concept in which user of a system feels 
to have a large physical memory(Main) that actually does 
not available.
for example U feel unlimited memory(Main) thougn u have 
only in MB's.

If OS did not have this concept then user has to manage the 
memory and in deed can run only a few program at a time.
It means here comes a limit on the efficiency of the system.

byeeeeeeeeeeeeeeeeee.

virtual memory is not only used for applications. Latest 
operations works using default virtual memory size 
allocated by the operating system at the time of 
installation. This will depends on total memory we are 
having in you system or server.

The best way is allocation of un-used partition for page 
file purpose.  Be sure no boday is accessing the 
partition.  This will increase system or server performance.

Don't remove pagefile settings this may cause system or 
server crash.
