Diskeeper, JkDefrag, PerfectDisk, UltraDefrag and every other WinXP/Vista defrag program use the Windows API for moving files around. It's not a defrag API, it's a "move this file from here to there" API, and it was not written by Diskeeper, but Microsoft. Only "defrag.exe" in Win95++ was written by Diskeeper for Microsoft.
Fortunately Microsoft has cut the Diskeeper connection with Vista SR1, and is using their own defrag program. I think the guys from Sysinternals (Contig, PageDefrag and Winternals Defrag Manager) who now work for Microsoft have something to do with the new defrag utility in Vista.
You can find plenty of alternatives to Diskeeper, most of which work better and cost less. Check out "The Great Defrag Shootout" for info.
