Whenever you defrag your hard drive (using the tool which ships with Windows), you might notice there is a big green block which not movable. For the most part this green block is your Windows page file. Typically the way to make sure this gets defragged is to simply “delete it” by (steps abbreviated) removing the page file, defragging the hard drive and then re-setup the page file. Instead of this workaround, defrag the page file directly by using Sysinternals PageDefrag tool.

This free tool does just what you think, defrags your page file:

PageDefrag uses advanced techniques to provide you what commercial defragmenters cannot: the ability for you to see how fragmented your paging files and Registry hives are, and to defragment them. In addition, it defragments event log files and Windows 2000/XP hibernation files (where system memory is saved when you hibernate a laptop).

This tool is ideal to run on a fairly regular basis to prevent your virtual memory and registry information from becoming too jumbled.

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.
