Nobody volunteer to say HOW is this thing doing!? Good, bad, !!
Well, I'll give it a try and see...

i've tried this, basic, fast and i like it

JkDefrag v3.16 (June 22, 2007)
Changes:
- Changed the message in the docs about the screensaver under Vista, it works if User Account Control is turned off.
- Bugfix in "-a 3" (fast optimize). It would not use Perfect Fit for gaps that were larger than all the data already processed.
- Bugfix in "-a 6" (move to end of disk). Files in zone 1 would not be moved.
- Added some translations of "Program Files" to the build-in list of SpaceHogs:
Archivos de programa (Spanish)
Arquivos de programas (Brazilian Portuguese)
Ohjelmatiedostot (Finnish)
Program Files (All others)
Program (Swedish)
Programas (Portuguese)
ProgramFiler (Norwegian)
Programme (German)
Programmer (Danish)
Programmes (French)
Programmi (Italian)
- Fixed a typo in the "System Volume Information" string in the SpaceHogs.
- Fixed the displaying of the zone number, should have been + 1.
For programmers:
- Changed the "makefile.bat" script, "JkDefrag.exe" does not need to be linked with "JkDefragScreenSaver.res".

If you find it complicated, I mean, if you would like to customize the defrag job you can try this GUI for JKDefrag. You have to download both, the GUI and JKDefrag. Then extract both in the same folder and run JKDragGUI.

Hope this helps!
