I copied the pictures from a DCIM folder (my camera card) and pasted them to a folder on my computer. Then I put the card back in my camera and deleted the pictures from the card. Then I somehow accidentally created a shortcut in the folder that I didn't want, so I hit undo to get rid of it. But instead, clicking undo emptied out the folder I had pasted the pictures into. Then I hit redo and it didn't do anything as far as I could tell. Is there any way to redo until I get those pictures back? Or any way to recover those pictures?
