Oh Come on no Response ?
You provided almost no details. There was nothing to work with.
When i insert a USB and open it on my Laptop i always see Shortcuts not the Original Files.
Where did these "original files" come from? How are you copying them? Are you seeing shortcuts directly in Windows Explorer, or only when you copy them?
If you want to copy them, you can select the files you want and then use the right-mouse button to drag them to the destination. When tou let go of the button you will be given a menu that let's you choose what to do (move here, copy here, create shortcut(s) here) of which you would want to second.
If the Alt key is stuck on the keyboard it could cause this to happen since Alt+Drag creates shortcuts rather than copying.
