BleachBit is a free and open-source disk space cleaner, privacy manager, and computer system optimizer. When your information is only your business, BleachBit guards your privacy.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. 

Uses
Use BleachBit to:

• disk space
• Reduce the size of backups and the time to create them by removing unnecessary files
• Maintain privacy
• Improve system performance (by vacuuming the Firefox database, for example)
• Prepare whole disk images for compression (common for "ghost" backups and virtual machines) by wiping free disk space

Cleaners
BleachBit includes a growing list of cleaners. Typically each cleaner represents an application such as Firefox or Internet Explorer. Within each cleaner, BleachBit gives options covering components that can be cleaned such as cache, cookies, and log files. Each option is given a description to help you make good decisions.

Many more cleaners for Windows and Linux are available in the CleanerML community repository.

Going beyond standard deletion of files, BleachBit has several advanced cleaners:

• Clear the memory and swap on Linux
• Delete broken shortcuts on Linux
• Delete the Firefox URL history without deleting the whole file—with optional shredding
• Delete Linux localizations: delete languages you don't use. More powerful than localepurge and available on more Linux distributions.
• Clean APT for Debian, Ubuntu, Kubuntu, Xubuntu, and Linux Mint
• Find widely-scattered junk such as Thumbs.db and .DS_Store files.
• Execute yum clean for CentOS, Fedora, and Red Hat to remove cached package data
• Delete Windows registry keys—often where MRU (most recently used) lists are stored
• Delete the OpenOffice.org recent documents list without deleting the whole Common.xcu file
• Overwrite free disk space to hide previously files
• Vacuum Firefox, Google Chrome, Liferea, Thunderbird, and Yum databases: shrink files without removing data to save space and improve speed
• Surgically remove private information from .ini and JSON configuration files and SQLite3 databases without deleting the whole file
• Overwrite data in SQLite3 before deleting it to prevent recovery (optional)
