OptimUSB overview

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. Run OptimUSB each time you eject.

When you delete a file from a USB drive on OS X, it is moved to the trash, leaving a blind copy on the USB 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 USB drive optimized and regain the actual disk space.

It gets the job done, but it performs rather slow although using a super fast Sandisk Extreme Pro usb 3.0 stick on a MBP 2014.

This seems to function almost exactly like Eject for Windows, a free program that deletes the hidden file on USB sticks. Having on the menu is interesting, but I've been used to having Eject for Windows on my Dock like the trash. It will clean and eject my disk in one motion.

After transferring photos off my SD card, this app efficiently deletes just those hidden Mac files and ejects the card. Keeps the card working at optimum speed, back in the camera.

I agree with the other commenters that this is somewhat misleading. Moreover, this can be done for Free if you know a bit of UNIX: cd /Volumes/[drive name] rm -Rf .* Then eject (or use the umount command while you're at it, heh). Note that if your drive's name contains spaces, you'll either need to enclose the whole path in quotes: cd "/Volumes/name with spaces" or you'll need to 'escape' the spaces by putting backslashes before them: cd /Volumes/name\ with\ spaces (This prevents Terminal from thinking that the spaces are there to separate three arguments: '/Volumes/name', 'with', and 'spaces', letting it know that the spaces are actually all part of one thing instead.)

The previous informed comments are all correct. This app DOES NOT "optimize" your flash drive. This is my vote that MacUpdate change the short description to not use the word "optimize" and that they overrule the developer description and remove any reference of optimization. TL;DR - App deletes .DS_Store; doesn't optimize storage; misleading description; waste of time.
