Help and Donate for the project

BleachBit is free and open source (libre) software, created and maintained by a community of passionate developers. That means that it is offered for free, its source code is freely distributable and modifiable (those are basic principles of libre/open source software).

You have at least two ways to support BleachBit :

  • by getting involved in its development and translations and joining the dev team, don’t hesitate to contact the team on the official website.
  • by funding the project through a donation to the official team. Even a small contribution is useful and gives courage… and helps small projects get bigger 🙂


You can also support free software (also called libre or open source) to be part of the revolution to fully open the software world. You may have already heard about some huge successes such as Firefox,, Ubuntu, GIMP, eMule… and thousands of other useful programs. So why not jump in and support the Free Software Foundation (FSF) ?

Beyond software, you can also help this big and essential tool that Wikipedia has become, an amazing wealth of information available thanks to the collective work of volunteers and donors.

Finally, for the most curious of you, here is the definition of what free software is. Revolutionary, isn’t it ? Thanks Mr. Stallman, and the millions of users and developers who followed his footsteps !

So many software suites claim to delete unneeded files from your system that it’s a wonder anyone has any junk in their trunks at all, if by « trunks » we mean those stubborn caches of files and folders that many of your programs and applications store in the out-of-the-way places of your hard disk and Windows installation. BleachBit is a free cache cleaner that’s designed to find, identify, preview, and delete unnecessary cached and saved files in your browsers and e-mail clients; programs like Java and Adobe Flash and Reader; communication tools like Skype, chat tools, and media players; and Google Earth, OpenOffice, and other miscellaneous apps, not to mention various system files.

BleachBit’s interface is efficient and cleanly configured; aside from File, Edit, and Help menus, there’s just a pair of icons marked Preview and Delete above a left-hand tree view of all our system’s accessible caches, each with a check box, and a main window that displays and previews files in a registry-like view. It identified and listed caches, logs, form histories, passwords, cookies, and other selections for Adobe Reader, Flash, Firefox, Google Chrome, Microsoft Office, and other programs. BleachBit also offered selections for Deep Scan and System, though the program advised that these processes are slow and that the System cleaner was experimental; we chose not to run these. However, there’s an entry for Windows Explorer that has some useful entries, including recently used items, thumbnails, and search history. We selected nearly everything else but our Firefox files (HINT: Don’t check Passwords if you don’t want them deleted) and clicked Preview. BleachBit displayed a fast-scrolling log of selected files. Seeing nothing critical, we clicked Delete, and BleachBit deleted 3,333 files in about a second, displaying a log on completion. The File menu offered options to Shred Files, Shred Folders, Wipe Free Space, or Shred Settings and Quit, which closed the program while eliminating our session data. The Preferences were fairly typical, except for a « Whitelist » that lets you specify file and folder paths that BleachBit will bypass.

BleachBit quickly and thoroughly purged files from our system that other cleaners had recently missed. It’s quite easy to select which files to delete and which to avoid, and the previews help ensure that you’re not deleting the wrong things.
