CleanRamDisk forces everything off the VD0: ramdrive.  It cleans it.  I
don't use it myself because I have enough memory (like you) but it
is there for people who want to force the ramdisk smaller.  Just deleting
files from VD0: doesn't do it because the space is not reclaimed when
the files are deleted.  The disk stays the same size and shrinks only
as other programs need memory.  This was explained as a performance
thing.  Why take the time to give memory back to the system if no one
else needs it and the ramdisk is likely to ask for it again later.  The
gradual shrinking is because unused ramdisk space is given back to the
OS slowly as other memory deallocations are made.  No big performance hit 
there.  

Course I could be all wet since this is from my memory of the docs.  Please
correct me where I got off course.
