Cleaning utilities, such as BleachBit, are great in freeing disk space, removing junk files, erasing your cache, deleting cookies and clearing your internet history. This all goes toward protecting your privacy.
BleachBit wipes clean 90 applications including Firefox, Internet Explorer, Adobe Flash, Google Chrome, Opera, Safari, and more. Beyond simply deleting files, 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. Better than free, BleachBit is open source.
It’s packaged in PortableApps.com Format so it can easily integrate with the PortableApps.com Platform. And it’s open source and completely free.
