Fast, low overhead, with many optimization strategies. Included are a set of easy to use scripts for endusers, a scripting engine for demanding users, a screensaver, and a combined Windows plus commandline version that can be scheduled by the Windows task scheduler or for use from administrator scripts.

MyDefrag (formerly JkDefrag) is able to handle USB sticks/disks and floppies.

What's New in This Release: [ read full changelog ]

· Added the Windows "bootstat.dat" file to the build-in list of special exceptions.
· To my great chagrin I have found that some programs can crash (most notably MySQL and uTorrent) if the disk on which they have open files is dismounted with the MyDefrag DismountVolume command. The command was used in the DataDisk scripts that were introduced in the previous version. I have now removed it.
