Nope, Windows does not use a Virtual Memory swap file in any mode *except*
386Enh.

In standard and real modes, Windows will swap when you switch to a DOS
application, saving the contents of the <640K area (since the magic
memory-moving virtual pages are not available) and of any XMS that the PIF
for the application requests.  (Note, to increase efficency, edit
_DEFAULT.PIF to use no XMS. (or EMS in 386Enh))  But Windows applications
are limited to your real, honest to God RAM.

In addition, some applications like Word for Windows and Corel Draw use the
TEMP directory while editing files.  This *is* a place where a RAM-disk will
help.  Corel Draw will *not* use my 11MB of RAM on my 80386SX, but I set up
a 3 MB RAMDRIVE as the TEMP and it runs about 3 times a fast on
moderately-sized files.  Other programs could benefit from this, as well.
Just check to see if they create temporary files on machines with >lots of
RAM available.
