MyDefrag Portable (JkDefrag) v3.36

MyDefrag is a disk defragmenter and optimizer for Windows.

It's completely automatic and very easy to use. MyDefrag is also fast, has low overhead and includes several optimization strategies. In addition to hard drives it can handle floppies, USB disks, memory sticks and anything else that looks like a disk to Windows. Included are a Windows version, a commandline version (for scheduling by the task scheduler or for use from administrator scripts), a screensaver version and a DLL library (for use from programming languages).
