JkDefrag - a unique and handy defrag tool

review from ClifNotes, Jun 2007, permalink Disk Cleanup


What was the first thing I thought when I ran the screen saver version of JkDefrag?


OH NO! I've screwed up my computer ...


Fortunately I was wrong. JkDefrag's interface is just so different than what I expected. It almost looks like one of the many psychedelic screensavers out there.


How well does it work? I really don't know, but it does seem to work. The cool part is how you can set it up as a screensaver. If your screensaver pops on a few times a day, your hard disk should remain fairly well defragged.


The program comes zipped up and there is no installation needed. After you unpack the zip file into a folder, you'll see a few executable files in it that you can run.



Windows version. This is what most people will use. No installation or configuration necessary, it's ready to run and will automatically process all the mounted, writable, fixed volumes on your computer



Commandline version. Specially designed to be run automatically in the background, or from administrator scripts.


JkDefragScreenSaver.exe + JkDefragScreenSaver.scr

Screen saver version. Move (or copy) these two files to the "system32" folder on your harddisk (usually "c:\Windows\System32\" or "c:\Winnt\System32\"). It will automatically become visible in the list of screensavers as "JkDefrag screensaver" and can be used just like any other screensaver (right-click somewhere on your desktop and select Properties, then select the Screen Saver tab).
