From the developer:
OptimUSB is an application that keeps your USB and memory cards optimized. You just need to run OptimUSB before ejecting your USB 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 USB drive is clean, optimized and ready to be removed safely.
Remember that OS X generates temporary files every time you connect your USB drive.
