JKDefrag is a file defragmentation utility for Windows. It is free and very ugly-looking but does the job very, very well. When you download this application it doesn’t get any easier as far as ease-of-use is concerned. There is nothing to install. Just double-click the JKDefrag.exe executable file and it starts doing its thing. This will surprise some people because most don’t expect an app to just work like this without some sort of installation first - but JKDefrag does what it’s supposed to do. You double-click and just wait until it’s finished. That’s it. Nothing else to do. It’s that easy.

See video below for an example of what to expect.
