I have a music folder on my externald HD. However when I tried to open it, it had nothing inside it. It takes a few seconds to open, as if it was reading something, but viola nothing. Also when I click on the folder itself it takes a few seconds as if there was something to read. But even the folder properties say nothing. I know it was there, I didn't delete it. What gives? I did a scan with AVG but it didn't find anything.
