Use BleachBit to:
Free disk space
Reduce the size of backups and the time to create them by removing unnecessary files
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
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.
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
