I consider this a program for advanced users. Be careful with it.

Multi-platform: Linux and Windows
BleachBit 0.8.3 cleans more Opera, WinRAR, Adobe Reader, Windows logs; improves wiping speed; adds menu options; add a Lithuanian translation; and updates other 18 translations.
The following changes have been made since 0.8.2:
* Wiping free disk space is now significantly faster. (The actual time will depend mainly on how much free disk space you have and how fast your disk is.)
* When wiping free disk space, show progress bar and estimated time to completion.
* To improve efficiency and maximize privacy, operations are now executed in this order: general cleaning, deep scan, RAM and swap cleaning, and free disk space wiping.
* Add menu option to wipe free disk space anywhere on the computer. One way this is useful is for wiping free disk space on removable media such as USB disks, or use it to avoid enabling the free disk space option checkbox (which most people should not use often).
* Add menu option to securely shred any folder (including all folders and files contained within) anywhere on your computer.
* Add context menu to options, so you can preview or execute individual options without changing any checkboxes. Just right click on an option (not a group of options) to see the new menu.
* Delete more icons found in Opera.
* Delete more URL history in Opera.
* Delete search history in Opera.
* Do not delete extension preferences in Google Chrome (which store configuration as HTML5 cookies).
* Fixed bug ‘[error 21] “is a directory” when shredding directories. (This bug existed only in version 0.8.2.)
* CleanerML (Cleaner Markup Language) now supports glob for walk.all and walk.files.
* Specific to Linux
