Disk cleaner

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.

Disk cleaners must not be mistaken with antivirus software (which delete malware), registry cleaners (which clean Windows Registry) or data erasure software (which securely delete files), although multifunction software (such as those included below) may fit into all these categories.
