MyDefrag (formerly known as JKDefrag) is a disk defragmenter and optimizer (a maintenance utility to make your harddisk faster) for Windows all versions. It is freeware, no time limit, fully functional, no advertisements. Fast, low overhead, with many optimization strategies, can handle floppies, USB disks, memory sticks, and anything else that looks like a disk to Windows.

⚠ Note: This product is not developed anymore and might not function properly.

If you are looking for alternatives, we recommend you to download DefragglerO&O Defrag or Smart Defrag.

Included is a set of easy to use scripts for end-users, a scripting engine for demanding users, a screensaver, and a combined Windows plus command-line version that can be scheduled by the Windows task scheduler or for use from administrator scripts.

MyDefrag is extremely solid because it is based on the standard defragmentation API by Microsoft. Most defragmenters are based on this API, including the free defragmenter that comes with Windows and many commercial defragmenters. Basically, all MyDefrag does is send "move this file to that location" commands to the API. The API is part of the operating system and can safely move almost any file on the disk, without risk, and while the computer is in full use.
