HiM (Hidden Cleaner iMproved) is a simple drag-and-drop utility that cleans and ejects USB devices like MP3 players, USB sticks... (and also local folders). Simply drag folders or removable devices into the main window or the application icon, and HiM will perform all the cleaning operations and (eventually) ejects the device.. It deletes the hidden files OS X creates like .DS_Store, etc. HiM is an improvement of Hidden Cleaner, on which is inspired, and comes also with a simple GUI. You can even customize the file list that you want to delete.
