MyDefrag 4.3.1 for Windows

MyDefrag is a powerful defragmenter and disc optimizer that's compatible with every version of Windows, from Windows 2000 to Windows 7. Best of all, it's completely free.

MyDefrag supports all kinds of devices, including hard drives, flash drives, floppy disks, memory sticks, or any other portable device.

MyDefrag effectively optimizes any given device, ultimately improving its performance even more than the Windows defragmenter. You can also schedule periodic maintenance check-ups on a daily, weekly, or monthly basis.

The application has three executables: one is the main application, another is for the command line, and the third is a screensaver for the aforementioned defragmentation.
