I use Diskeeper a couple of times a week and have done for years. It has
never had bad any effect in IV.
I would avoid using System Mechanic et al. where there is a combination of
registry cleaning, defragging and other things combined. Some of the
registry cleaners are doubtful and I have been burned although Registry
Mechanic seems to work. Any work on the registry should be done with care
:-)
