UTILITY SOFTWARE

Disk defragmenters - Examples include a Disk defragmenter which can detect computer files whose contents have been stored on the hard disk in disjointed fragments, and move the fragments together to increase efficiency; a Disk checker can scan the contents of a hard disk to find files or areas that are corrupted in some way, or were not correctly saved, and eliminate them for a more efficiently operating hard drive; a Disk cleaner can find files that unnecessary to computer operation, or take up considerable amounts of space. Disk cleaner helps the user to decide what to delete when their hard disk is full.

System Profilers - A System profiler can provide detailed information about the software installed and hardware attached to the computer. Backup software can make a copy of all information stored on a computer, and restore either the entire system (e.g. in an event of disk failure) or selected files (e.g. in an event of accidental deletion). Disk compression software can transparently compress the contents of the hard disk, in order to fit more information to the drive.
