Free Defragmentation Utilities / Free Defragmentors / Free Defrag
The free defragmentation utilities listed on this page purport to defragment your hard disk, that is, they move the various fragments of your file so that they are in one contiguous chunk. A defragmented hard disk has at least a couple of advantages over a badly fragmented one: your system may operate faster, since the operating system does not have to move the drive head of the drive all over the hard disk to load the different portions of a file, and it is generally slightly easier to recover an accidentally deleted file, since the various segments of the file are placed in contiguous clusters.
Be aware also that if you use Windows, you already have a defragmentation tool installed; Windows comes with a somewhat slow but otherwise functional defragmentation utility. It also works automatically in the background without your intervention. If you are a novice or casual computer user, this built-in utility is more than adequate. In fact, they are probably even adequate for "power" users.
In addition, defragmenters are only useful on systems with normal (magnetic) hard disks. Reorganizing file fragments does not lead to any speed-up on solid-state drives, that is, SSDs. The system does not have to move any drive heads to access data on such drives, and indeed there are no drive heads on SSDs in the first place, so whether a file is fragmented or not is irrelevant. Trying to consolidate file fragments in such a case merely leads to needless wear-and-tear on your drive, shortening its life, with no extra benefit.

- WinContig
WinContig allows you to defragment your hard disk, folders and/or individual files. It works on Windows 2000, XP and Vista. You can also use Windows Task Scheduler to create defragmentation schedules. It can either (at your option) defragment a file into the first free area it finds, or look for an area that best fits the file you are defragmenting. If there is no space big enough to fit the defragmented file, it will try to defrag as much of the file as possible.
- UltraDefrag
UltraDefrag is a defrag tool for Windows that also includes a boot-time defragmenter for degragmenting files that are locked during normal Windows operation. It is released with source code and is distributed under the terms of the GNU General Public License.
- Contig
Contig is a command line defragger for Windows. You invoke it from a Windows command prompt with the name of the file you want defragmented. It's useful if you don't want to run the built-in Windows defragmentation tool just to defragment a single file.
- SpeeDefrag
SpeeDefrag is a program that restarts your computer and runs only the Windows defrag program. With only the Windows defragmenter running, defragmentation will presumably run faster (provided you don't count the time it takes to reboot the system). You can also schedule the defrag run, as well as shutdown the computer after defragmentation. The program runs under Windows XP, Vista, 7 and 8.
