What is a disk defragmentaer?

Windows Disk Defragmenter is a computer program included within Microsoft Windows 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, or defragmenting. The purpose is to optimize the time it take to read and write files to/from the disk by minimizing head travel time and maximize the transfer rate.



The technique used by the Disk Defragmenter are as follows



1. Moving all the index or directory information to one spot. Moving this spot into the center of the information, i.e. one third of the way surrounded by, so that head travel to facts is halved compared to have directory information at the front.

2. Clustering files around the directory area.

3. Moving infrequently used files further from the directory nouns.

4. Obeying a user provided table of file descriptions to underscore or ignore.

5. Making files contiguous so that they can be read minus unnecessary seeking.
