OptimUSB is an application (in English, Spanish, Italian, French, German and Japanese) that keeps your USB, external drives and memory cards optimized.
You just need to run OptimUSB before ejecting your external drive. Any Mac or Windows temporary files get deleted (.DS_Store, .Trashes, .Spotlight-V100, Thumbs.db, etc.).
OptimUSB then automatically ejects your drive. Now, your external drive is clean, optimized and ready to be removed safely.
Remember that Mac OS X generates temporary files every time you connect your external drive. Run OptimUSB each time you eject.
When you delete a file from a external drive on Mac OS X, it is moved to the trash, leaving a blind copy on the external drive. You could completely empty the trash, but you would lose any other files in the trash as well. That is why deleting items does not help you regain space. With OptimUSB, you can keep your external drive optimized and regain the actual disk space.
