Hi, I am not 100% sure of this, but I think it may have happened if you
used the -normal- defrag mode on a volume shadow copy (VSS) enabled
volume. When defrag commences, I -think- the VSS makes backup copies of
files that are being moved about or something, and that causes an
increase in space occupied.
It's best if you use the -VSS -compatible- defrag mode of Diskeeper
2008 with Vista to avoid conflict between defragmentation and VSS. Not
many defraggers have this very useful option- Diskeeper is one of the
very few, if not the only one.
Again, let me reiterate that this is only a guess, you may want to
double check the VSS-Diskeeper thing.
