USBclean

The most powerful USB cleaning utility ever made! Quickly and easily remove pesky junk and ghost files from your external USB drives. .DS_Store, Thumbs.db, .Spotlight, and trashes files take up precious space, and can cause issues on some devices. Remove any number of pre-configured filetypes, or add your own custom filetypes for more flexibility.

USBclean is useful for

*cleaning annoying files which don’t play on your media devices.
*removal of Mac only files (useful when sharing USB drive with a friends PC).
*removal of Windows only files which take up useful space
*removing files of any number of (customizable) filetypes.[for instance, to quickly remove all m4a files from an external drive, go to the “File Types” preference-tab and quickly add “m4a” to the extensions field]
