MyDefrag (formerly JkDefrag) is a disk defragmenter and optimizer for Windows. Completely automatic and very easy to use, fast, low overhead, with several optimization strategies, and can handle floppies, USB disks, memory sticks, and anything else that looks like a disk to Windows.

Very thorough defragmentation and optimization with impressive performance benefits. Safe and reliable due to use of Windows defrag API. No option to shut down PC on completion. 'No frills' interface. The best free application I have found for defragmention and optimization only. Ideal for IT professionals but general users may prefer more the user-friendly interfaces and additional functionality of alternatives such as 'Auslogics Disk Defrag'.

The product eliminated many free space elements. Retrieved about 15% more disk after another defragger. Slow It took four days to defrag a 600mb external hard drive. Other the slowness I think that this is an excelent defragger. It eliminates many space eaters that other defraggers do not. MyDefrag 4.2.9 runs faster once it does not have to get through all the old defrag errors. It save a lot of space by combining smaller freespaces

Easiest Defragger I've ever used. Fastest as well. Works particularly well in Safe Mode.Easy download. Easy learning curve. If you use System Restore, depending on your OS, you may lose its functionality as many or all restore points may vanish if you select a performance level that includes Optimization. No support other than a small users forum. Beats the pants off of Windows Defrag and easier to use than it's competitors. But if you go with its Optimizer level, you may find it incompatible with System Restore points, useful to have working when your OS destabilizes.
