Fragmentation after DF is higher than before

After I use DF my disk fragmentation is higher then when it started and I am loosing disk space. I have tried 5 times with the 2 different version (Haven't tried the new one yet). I figured out that when DF gets to 80% it either stops or it finishes within 2 minutes. I have looked on the forums and have checked the Stop VSS and both in the custom settings.

Any help?

What version of windows?

run DF with the PC in Safe Mode and see if it performs better.

What percentage is your system restore space set at?

Use disk clean up

select 'more options' and select to clean up all but the last restore point.
