A '''disk utility''' is a [[utility software|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 letter]]s and other [[mount point]]s, renaming volumes, [[disk checking]], and [[disk formatting]], which are otherwise handled separately by multiple other built-in [[command (computing)|command]]s.<ref>{{cite web|last1=Gerend|first1=Jason|last2=Tobin|first2=John|title=Overview of Disk Management|url=https://docs.microsoft.com/en-us/windows-server/storage/disk-management/overview-of-disk-management|website=Microsoft|accessdate=22 March 2018|date=12 December 2017}}</ref> Each [[operating system]] (OS) has its own basic disk utility, and there are also separate programs which can recognize and adjust the different [[filesystem]]s of multiple OSes. Types of disk utilities include disk checkers, disk cleaners and disk space analyzers
==Disk cleaners==
Line 9 ⟶ 10:
Disk space consuming unnecessary files include [[temporary file]]s, [[trash (computing)|trash]], old [[backup]]s and [[web cache]]s made by web browsers. Privacy risks include [[HTTP cookie]]s, [[local shared object]]s, [[Computer data logging|log files]] or any other trace that may tell which computer program opened which files.
Disk cleaners must not be mistaken with [[antivirus software]] (which delete [[malware]]), [[registry cleaner]]s (which clean [[Microsoft Windows]] Registry) or [[data erasure]] software (which securely delete files), although multifunction software (such as those included below) may fit into all these categories.

'''[[Disk formatting]]''' and '''[[disk partitioning]] tools''' are responsible for generating low level disk layouts and [[file system]]s. Operating systems typically supply one or more programs performing these functions as part of their standard install:

==Disk space analyzers==
[[File:
A '''disk space analyzer''' (or '''disk usage analysis software''') is a [[software utility]] for the visualization of [[disk storage|disk]] space usage by getting the size for each [[Folder (computing)|folder]] (including sub-folders) and [[Computer file|files]] in a folder or drive. Most of these applications analyze this information to generate a graphical chart showing disk usage distribution according to folders or other user defined criteria.
Some disk space analyzers like DiskReport allow analysis of history of size and file count for each folder, to help find growing folders.
Examples:
* Directory Report
* WizTree
* DiskReport
* GNOME [[Disk Usage Analyzer]]
* KDE [[Filelight]]
* [[WinDirStat]]
* [[SpaceSniffer]]
* TreeSize
