RE: Diskeeper - Weird Results

This is my last defense of DK.  I always check my fragmented files in the
text display.  They are very few and small.  Today only 2, both 1kb in size.
Both are in the directory where DK says they are.  This program did not work
for me in manual mode when I first bought it.  But after I used the SEt and
Forget scheduler and ran it a few days everything was fine.  This program is
really designed to run in the background every day or several times a day.
It does defrag open files.  Personally I run it every day on my regular
computer and continuously all night while the mkt is closed on my trading
computer.  This solved all my fragmentation problems and significantly
speeded up both computers and especially Ts2k.  The free version DK Lite is
probably not going to make everybody happy.  I think the pay version is
worth it.
