Quick question. I had a folder that I used to store videos in. I would add to it constantly, and it always worked fine. Then one day I added two or three smaller videos, and when I went back to open the folder again, it would not open. I would click on it and the little sand timer logo thing would pop up and just stay there for like five minutes- with nothing on the screen ever changing, then finally, it would say "Windows Explorer has stopped working and needs to restart." I ended up deleting the file, and then copying it back after I took some stuff out, and it works fine now. I scanned it with five different anti-spyware and anti-virus programs, and nothing ever showed up. Any ideas on what it might have been?
