Disk utility

A disk utility is a utility program that allows a user to perform various functions on a computer disk, such as disk partitioning and logical volume management, as well as multiple smaller tasks such as changing drive letters and other mount points, renaming volumes, disk checking, and disk formatting, which are otherwise handled separately by multiple other built-in commands. Each operating system (OS) has its own basic disk utility, and there are also separate programs which can recognize and adjust the different filesystems of multiple OSes. Types of disk utilities include disk checkers, disk cleaners and disk space analyzers

Disk cleaners

Disk cleaners are computer programs that find and delete potentially unnecessary or potentially unwanted files from a computer. The purpose of such deletion may be to free up disk space, to eliminate clutter or to protect privacy.

Disk space consuming unnecessary files include temporary files, trash, old backups and web caches made by web browsers. Privacy risks include HTTP cookies, local shared objects, log files or any other trace that may tell which computer program opened which files.
