This is a simple free disk defragmentation tool that you can use to keep your internal or external drive in order Optimisation will bring all the files together in one place, leaving the rest of the hard disk empty, and will sort the files, for example alphabetically. This is exactly what happens on your hard disk, the files that belong to an application can be all over the place, anywhere on the hard disk. There is an index telling you exactly where every book is, but you will have to walk a lot when you need several books. Imagine a big library with lots of books, spread out all over the building and not sorted whatsoever.

The API is part of the operating system and can safely move almost any file on the disk, without risk and while the computer is in full use. Basically all MyDefrag does is send 'move this file to that location' commands to the API. Most defragmenters are based on this API, including the free defragmenter that comes with Windows and many commercial defragmenters. MyDefrag is extremely solid because it is based on the standard defragmentation API by Microsoft, a system library that is included in Windows 2000, 2003, XP, Vista, 2008, and Win7. Included are a set of easy to use scripts for end-users, a scripting engine for demanding users, a screensaver, and a combined Windows plus command line version that can be scheduled by the Windows task scheduler or for use from administrator scripts. Fast, low overhead, with many optimization strategies, can handle floppies, USB disks, memory sticks, and anything else that looks like a disk to Windows. It is freeware, no time limit, fully functional, no advertisements. MyDefrag is a disk defragmenter and optimizer, that is a maintenance utility to make your hard disk faste).
