Uhm, why waste time developing a disk defragmenter tool for jv16? PerfectDisk, O&O Defrag and Diskeeper are excellent alternatives to the 5 year old Windows standard! PerfectDisk is at v7.0.46 right now but v8.0.30 will be released on the 12th. It has options that no other defragmenter has.

If jv16 wants to make a brand new feature, make a registry defragmenter. I currently use NT Registry Optimizer but if jv16 can code one that outperforms it, that would be great. I am shocked jv16 would even consider bothering with a disk defragmenter with the *awesome* alternatives out there...
