This guide shows how you can install and use BleachBit on an Ubuntu 9.04 desktop to delete unnecessary files. BleachBit deletes unnecessary files (such as cache, cookies, Internet history, localizations, logs, temporary files, and broken shortcuts) to free valuable disk space, maintain privacy, and remove junk. It wipes clean Adobe Reader, APT, Bash, Beagle, Chromium, Epiphany, Firefox, Flash, GIMP, Google Earth, Java, KDE, OpenOffice.org, Opera, RealPlayer, Second Life viewer, Skype, VIM, XChat, Yum, and more.
