usb copier

I need a usb that when i insert it to another computer it copies all the other usb information wheter they were in the computer or connected later, ive done some code edtiting and im having some troubles doing what i want.......Let me try to explain ......im goign to a history class were the teacher doesnt give us his notes so i would like to copy them , and if possible to copy into a folder with stealth or either cfg/ert/fcu/jng... or something like that, if anyone have better ideas please let me know. .... oh it is for windows and of course teachers have their own passwords and login name wich they type as they enter the class. its something like usbdumper but without installing anything just connecting the usb. Thanks for all This are the files wich i tried to make in an attemp to do what i want
