BleachBit Overview
BleachBit is a free, open-source system-cleaning utility for Windows and Linux, often described as an open-source alternative to CCleaner. It frees disk space and protects privacy by deleting temporary files, caches, browser histories, cookies, logs, and other unneeded data from the system and many applications. Beyond simple cleanup, it can shred files to prevent recovery, wipe free disk space to erase traces of previously deleted files, and vacuum certain databases to make them smaller and faster. Advanced users can write custom cleaners. It is a capable, no-cost privacy and cleanup tool. The full BleachBit installer is self-contained and finishes installation even on an offline machine. A command-line interface allows scripted cleaning, and a preview shows exactly what will be removed before you commit to it. This page links straight to BleachBit's official BleachBit source.
