BleachBit frees disk space, removes hidden junk, and guards your privacy. Erase cache, delete cookies, clear Internet history, remove unused localizations, shred logs, and delete temporary files.
Designed for Linux and Windows systems, it wipes clean over 50 applications including Firefox, Internet Explorer, Flash, Google Chrome, Opera, Safari, Adobe Reader, APT, and more.
