Plug in usb stick into an open usb port on your computer. If a screen does not open up showing the contents of the drive then you can find it under my computer. (it will say removable drive with a letter) open this up and right click on file you want to delete and select delete. Do this for each file you want to delete.

Remember to hit the THANKS button if my post was helpfull (Or annoying...hehe)
