Free Hard Drive Clean up Tool. Bleachbit

Bleachbit

Bleachbit is a cross-platform (Windows and Linux) cleaner. It has been my experience that Bleachbit does the best job (of all available tools) of freeing up the most space. Bleachbit not only frees up space, but helps to keep private your data by clearing all available caches, deleting cookies, clearing Internet history, shredding temporary files, deleting logs, and discarding junk. Bleachbit also has the ability to wipe unallocated disk space in order to improve compression ratio for disk image backups. Cost: Free.
