Hi,
We have been runing SBS2000 for a number of years.  The C
drive is only 4 Gb.  All programs (Exchange, SQLServer
etc) are installed on the D drive.  The only thing on the
C drive is the OS.  We have about 980Mb of free space on
C.  Whenever I run a security update, I move the unistall
files from C to D.  To do this I use "Ctrl-X", "Ctrl-V"
(to move the files) After doing this the last time I
noticed I didn't gain any free space (although I moved a
number of files from C to D).  So, I did a "Ctrl-C", "Ctrl-
V" on the D drive files to a new folder on the D drive.  I
then deleted the old files.  After finishing, I looked at
my free space on C and it agained 50Mb. BUT THAT IS AFTER
MOVING FILES ONLY ON THE D DRIVE!?!?  When you use Ctrl-X
to move files between drives, is it just a pointer and the
space is still stored on the original drive?  If so, that
is bad.

I then summed up all the space for each folder on C and it
only comes to about 1.5Gb, viewing the properties on C, it
shows used space as 3.2Gb.  Where is the remainder of
space?

This isn't a huge issue (we have been around 1Gb free
space for a long time) but I'm curious how the OS
calculates free space.
