I've used this very quick, if it really does have code by the sysinternals team this really is a solid piece of software.
Power Defragmenter is based on Sysinternals defragmentation "engine".
Basically its just a very advanced GUI for the Sysinternals core application which takes defragmentation process to a whole new level. Very high defragmentation speed, efficiency and ease of use.
Such high speed is only available with Sysinternals defragmentation "engine".
Thanks again to Sysinternals Mark Russinovich and Bryce Cogswell.
Version 1.8 features new PowerMode which provides even higher defragmentation rate.
Power Defragmenter is a stand-alone application (extract&use) which works only in Windows 2000/XP
