phish...ntfs handles files so differantly, microsft didn't even want to put a defrag utility in the nt kernal in the first place, as they didn't see a need.

diskeeper struck a deal with ms, and gives them the utility for free, so that they can get the free advertisement.

this is the reason you cannot schedule a defrag in xp.(ha...my batch file foils that strategy)

the deal is, leave that feature out, so people might be more inclined to purchase the commercilal diskeeper
