Disk Defragmenter

Disk Defragmenter

"Features:

* Can be run by any user (service needs to be installed by an administrator).
* Complete whole-disk defragging, including private operating system files.
* Multiple instances can be run simultaneously (if you have multiple disks).
* Individual file defragging, with wildcards and recursion. This mode is an opportunistic defragger, marginally better than Diskeeper in that it will at least defrag the file as best it can rather than not at all.
* Defrags NTFS, FAT** and FAT32** filesystems on any media (HD, ZipTM/JazTM, Floppy, etc).
* A "shotgun" mode, where it severely fragments files. Useful for testing or really annoying someone.
* Individual file fragmentation analysis. Find out where on disk a file resides, and how many fragments it's in.
* 100% safe and interruptable. This program doesn't actually move the files - the OS does it. Even if you suffer a power failure while it's working, you run no higher risk of file system corruption than you would if you had happened to be saving a file from any application.
* Boot-time defragmentation. "

Interesting free Disk Defragger for XP/2003. (It appears it might work on Win2K, since it's based on the NT Disk Frag API, but it's not 100%. And I'm to chicken to test it ;)

Will have to give this a try as I'm to cheap to buy a full defragger.
