I did that and it did not work. I also plugged it in and looked in it on a windows 7 computer and the same thing happened. My computer is windows 8. Does windows 8 have anything to do with this?!?!?!
On my Windows 8, occasionally it will load the folder before loading everything in the folder, and it might even look blank for minutes, saying "Folder is empty"(Paraphrase) before the green progress bar loads fully, and everything's there. Especially if you have large files, or have not rebooted your computer in a while, or have recently put files there that aren't small filesizes, will it do this. So try having it be in the folder and just waiting for a few minutes for it to load; you can do something else while waiting; it won't effect it.
