Cleaner , a disk cleaner A disk cleaner deletes unnecessary or unwanted files to free up disk space, reduce clutter, or protect user privacy. Such files may include
temporary files,
trash, old
backups,
web caches, and privacy-related data such as
HTTP cookies,
local shared objects, and
log files. Disk cleaners are distinct from
antivirus software (which deletes
malware), a
registry cleaner (which cleans the
Windows Registry) or
data erasure software (which
securely deletes files).

Linux Checker A disk checker attempts to identify and correct invalid or corrupted disk areas and should not be confused with a
disk cleaner, which deletes unnecessary files. Some disk checkers can perform a whole surface scan to attempt to find any possible
bad sectors, whereas others scan only the logical structure of files on the hard disk. Operating systems often include one such tool. For example: •
CHKDSK •
fsck Layout , a front-end for GNU Parted
Disk formatting and
disk partitioning tools generate low-level disk layouts and
file systems. An operating system typically supplies one or more of such utilities. Windows: •
Logical Disk Manager •
format •
fdisk •
diskpart MacOS: •
Disk Utility Linux: •
Logical Volume Manager •
GNOME Disks •
GNU Parted Space analyzer , a disk space analyzer that uses sliced pie charts A disk space analyzer (or disk usage analysis software) visualizes
disk space usage by directories (including subdirectories) and files on a drive. Most such utilities generate graphical charts showing usage distribution by directory or other user-defined criteria. Some disk space analyzers, such as DiskReport, also allow analysis of directory size and file count over time. Examples: • Directory Report • WizTree • DiskReport • GNOME
Disk Usage Analyzer • KDE
Filelight •
WinDirStat •
