Task Manager is the seay way to get a quick idea of what's running
on your machine and how big each one is;
Right Mouse Click on the task bar, pick task manager. The process tab
tells you what and how big, the performace tab tells you how much
memory you have left.
For a deeper understanding run perfmon.exe
When I know what my requirements are I like to set the MIN amd MAX
equal, then do a stand-alone defrag to make one big swap file. I've
seen developer's systems with the swap file broken into litterly
hundreds of fragments.
I can imagine a memory manager that would actually take advantage of
parts of the pagefile.sys spread around on the drive to minimize
seek time, but if I'm right I doubt that XP does it.
