Free defragmentation tool software for windows

DefragMentor Lite CL is a free command line file defragmentation tool that will help you defragment a single file or a group of files as well as to obtain information on file and disk fragmentation. DefragMentor Lite CL (where CL stands for Command Line) is a perfect tool for automated file-based defragmentation.
Even if you defragment the entire disk on a regular basis, some frequently changed files become fragmented long before the next launch of disk defragmenter. So you can use DefragMentor Lite CL to optimize placement of individual files thus reducing access time and improving overall performance of your system. Database files of any kind (especially large ones) are the best example of what DefragMentor Lite CL can optimize.
Instead of running DefragMentor Lite CL manually every time you need to defragment files you can schedule a task, which Windows will run for you automatically at any convenient time. Use the standard Windows task scheduler if you want to work in this way.

One of the limitations of the Windows NT/2000 defragmentation interface is that it is not possible to defragment files that are open for exclusive access.
Thus, standard defragmentation programs can neither show you how fragmented your paging files or Registry hives are, nor defragment them.
Paging and Registry file fragmentation can be one of the leading causes of performance degradation related to file fragmentation in a system.
PageDefrag uses advanced techniques to provide you what commercial defragmenters cannot: the ability for you to see how fragmented your paging files and Registry hives are, and to defragment them.
In addition, it defragments event log files and Windows 2000/XP hibernation files (where system memory is saved when you hibernate a laptop).
PageDefrag works on Windows 2000, Windows XP, Windows NT 4.0 and Server 2003.
Installation and Use
When you run PageDefrag (pagedfrg.exe) you will be presented a listbox that tells you how many clusters make up your paging files, event log files, and Registry hives (SAM, SYSTEM, SYSTEM.ALT, SECURITY, SOFTWARE, .DEFAULT), as well as how many fragments those files are in. If you feel that these files are fragmented enough to warrant a shot at defragmenting them, or if you want to defragment them at every boot, select the appropriate radio button choice and click OK.
When you direct PageDefrag to defragment, the next time the system boots it will attempt to do so. Immediately after CHKDSK examines your hard drives PageDefrag uses the standard file defragmentation APIs (see my Inside Windows NT Disk Defragmenting page for documentation of these APIs) to defragment the files.
As it processes each file PageDefrag will print on the boot-time startup screen the file name and its success at defragmenting it. If it is successful at reducing the fragmentation it will tell you the number of clusters the file started with and the number it consists of after the defragmentation.
In some cases PageDefrag may be unable to reduce fragmentation on one or more of the files, and it will indicate so on the boot-time Blue Screen.
This can happen either because there is not enough space on the drive for defragmentation, or the free space itself is highly fragmented.
