Disk defragmenter

From Wikipedia, the free encyclopedia

A disk defragmenter is a computer program designed to increase access speed (and sometimes increase the amount of usable space) by rearranging files stored on a disk to occupy contiguous storage locations. Disk defragmenters are available for many platforms, the most common being those included with operating systems (i.e. Microsoft Windows), utility packages (like Norton Utilities), or other standalone defragmenters (like PerfectDisk or Diskeeper). Many offer advanced options, such as sorting by last access or modification date to decrease access time for most commonly accessed files.
