Bleachbit
BleachBit is a system cleaning tool that frees disk space by removing accumulated cache, cookies, logs, temporary files, and other unnecessary data. It provides a preview of what will be deleted before any permanent changes are made, allowing safe review and adjustment of cleaning operations.
The tool offers extensive control over what gets cleaned, including the ability to exclude specific files and folders, create custom cleaning rules for files not covered by built-in cleaners, and import over 2,400 community-maintained cleaning rules from winapp2.ini files. It supports secure data erasure through file overwriting and shredding, as well as wiping free disk space to prevent recovery of previously deleted files. Browser cookie management allows selective preservation of cookies from chosen hostnames to maintain login sessions while removing tracking data.
BleachBit can be operated through a command-line interface for scripting and automation, with support for wildcard-based selection of cleaning options and exclusion lists. It also offers scheduled cleaning via system task schedulers, context menu cleaning for individual files or folders, and deep filesystem scans for thorough cleanup. The tool includes update checking and automatic refresh of cleaner definitions to keep cleaning rules current.
