BleachBit: File Removal and Application Data Cleaners
While BleachBit is known widely for its role in deleting email from Hillary Clinton's server, it is used routinely to free up disk space on hard drives, improve system performance, and remove private files irreversibly.
Unlike physically destroying or overwriting an entire drive, BleachBit removes files in systems that must continue to work. It also wipes clean the free space on your drive that likely contains old, but recoverable data.
BleachBit is a free, open source program, built with a collection of cleaners for specific applications. It was created by Andrew Ziem, and released as a Linux utility in 2008. BleachBit cleans files created by the operating system and installed applications.
File Removal Services:
A simple "delete" of a file does not remove it from your computer. That is why deleted files can often be recovered, and free space is not always empty.
Numerous applications create a backup copy of the existing file, prior to saving a newer version. The existing file, e.g. "file.html", is preserved with a new name, such as "file.html.bak" and "file.html.old". There is no standard naming convention for backup files; you have to know the backup designation your application uses.
Information you want to delete may also be contained in backup files in the cloud or storage media, recycle bins, and in free space on a drive. It is difficult to know what to look for, and where to find every instance of the data you want to remove. Different files, with the same filename, can coexist on a computer, as long as the files are in separate folders.
If you want to delete all versions of a specific file (with certainty), you need to know a lot about the operating system and application that created the file.
Do you have files on your hard drive that need to be shredded and removed permanently?
We can help you use BleachBit effectively on Linux and Windows computers.
BleachBit is distributed with cleaners for popular applications such as Chrome, Flash, MySQL, and Skype. Programmers can write and incorporate their own cleaners, and submit their code for review and sharing with others in the open source community.
Application cleaners for the newest BleachBit releases are created in an XML-based markup language, CleanerML. An examination of the source code for the Internet Explorer cleaner shows how it removes cookies, form history, browsing history and temporary files.
