I had a preinstalled copy of Diskkeeper but it just would not perform and I wanted the ability to defrag my system files completely. Perfect disk did this without any problems and it has the best and easiest GUI. The scheduling process is very easy also....
Off line defrag of system files rocks. You will not be disappointed.
