yes, you can drop anything you like onto mp3sorter's desktop icon : files, folders, drive icons or any combination.
Then it shows the % in the title row and after processing it says "finished".
Whatever you dragged onto it is now properly sorted on the drive.

Using it with files on your hard disk is (of course) much faster than on a flash drive. But using it directly on a flash drive is also possible.
I normally copy some files over to my player and then drag the whole flash drive icon to it, then go and make some coffe ;-)
