Free command line defrag utility

JKDefrag

The long-awaited version 4 is finally out. The program is now called "MyDefrag", because it has a scripting language and you can customize just about every aspect of it. It is no longer the "JK" (Jeroen Kessels) defragger, but "my" (your) defragger!

* Fully functional freeware.
* With scripting language.
* Improved interface.
* Higher speed.
* Better optimization.
* Lower memory usage.
* Extensive documentation.
* Easier to install.
* .... and more!
