- defragmentationsearch for term
-
The process of rewriting parts of a file to contiguous sectors on a hard disk drive. Defragmentation is done to increase disk speed access and retrieval. For example, when files are updated, updates are typically saved on the largest continuous space on the hard disk, often on a different sector than other parts of the file. When files are fragmented like this, a computer must search the entire hard disk each time the file is opened to locate all of its parts, which slows down response time considerably. Routine disk defragmentation is recommended.
