I fix, upgrade, clean, defrag, etc. computers (most of them come with XP)
donated to a Sharing Center in my church. These are then given away for free
to people who need them.
Usually I take out any programs and files that appear to be superfluous to
my clients (their needs are limited). Still, usually over 5 GB on a typical
HD remain.
When I do a fresh install, I fill less than 3 GB with XP and some other
useful programs my clients will need.
I have always wondered how to explain the difference of, let say 2 GB +,
between the two cases.

Any explanation will be gratefully accepted.
