Windows PC upkeep – open source JKDefrag

Windows users are quite familiar with the need to defrag the hard drive every once in a while. It is specially important if you’re moving large files (like movies), installing, and removing programs. Linux though doesn’t have to worry much about this.

In the open source world, you can also find a very nice tool that will help keep your windows running smoother. JKDefrag is a pretty small, nice, and effective, defrag utility program. You can use it without any installation, just by running the JkDefrag.exe, have it as your screen saver running every time your computer is idle, or you can install it like any other software.

While it is running you’ll be able to see what is going on and see how much of a mess the hard drive is in. If it is pretty fragmented, run it a couple of times and it will get better.


You can use it on Windows 98, 2000, XP, or Vista. Better yet, you could do away with Windows and go to Linux without having to worry about this, but that is a whole different blog post. 🙂
