Many of you are probably sitting in front of a computer that has the amazing CCleaner application (review) installed. It helps keep your computer free from clutter by deleting unimportant files and cleaning up the registry, which is especially useful after uninstalling a program.

The same people who brought you CCleaner have also thrown down the gauntlet on defragmenting. Defraggler Beta is a free app that, as expected, will defragment the files on your computer. It’s unique in that it lets you specify individual files to defragment, which are displayed in a list with the most fragmented first. By using this method you can get the most out of the defragmentation in as little time as possible.

One of the more interesting things is clicking on the filename listed at the bottom of the window. Doing so will highlight the fragmented blocks that correspond to that file on your hard drive, and you’ll probably find it interesting to see how spaced out specific files are.

Defraggler does require a quick installation, but after that you can grab the single executable file located in the Program Files folder and throw it on your USB drive. Everything is contained in that one file to promote portability, just like CCleaner! It supports 32-bit versions of Windows 2000/2003/XP/Vista, and can handle both NTFS and FAT32 formatted drives.
