In the maintenance of file systems, defragmentation is a process that reduces the degree of fragmentation.It does this by physically organizing the contents of the mass storage device used to store files into the smallest number of contiguous regions (fragments, extents).
The command line utility, Defrag.exe, offers more control over the defragmentation process, such as performing a full defragmentation by consolidating all file fragments regardless of size. [14] This utility can be used to defragment specific volumes or to just analyze volumes as the defragmenter would in Windows XP.

Fragmentation can be remedied by re-organizing files and free space back into contiguous areas, a process called defragmentation. Solid-state drives do not physically seek, so their non-sequential data access is hundreds of times faster than moving drives, making fragmentation less of an issue. It is recommended to not manually defragment solid ...
Defraggler is a freemium defragmentation utility developed by Piriform Software, which can defragment individual files or groups of files on computer memory systems. Defraggler runs on Microsoft Windows; it has support for all versions since Windows XP. It includes support for both IA-32 and x64 versions of these operating systems.
Unlike the Windows built-in defragmenter tool, Contig can defragment individual files, individual directories, and subsets of the file system using wildcards. Contig does not move any data except that belonging to the file in the question, so the amount it can defragment a file is limited to the largest contiguous block of free space on a system.
If the page file is fragmented, PageDefrag can take as long or longer than Windows Defrag. However, a defragmentation of the page file can improve performance much more than defragmentation of the Registry will. PageDefrag does not defragment the contents of the registry files, only the placement of these files on the hard drive.
