BleachBit Clean your OS
BleachBit quickly frees disk space, removes hidden junk, and easily 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 70 applications including Firefox, Internet Explorer, Flash, Google Chrome, Opera, Safari, Adobe Reader, APT, and more.
Beyond simply deleting files, BleachBit includes advanced features such as shredding files to prevent recovery, wiping free disk space to hide traces of files deleted by other applications, and vacuuming Firefox to make it faster.
