I copied a file from my mp3 jukebox to my computer, and the folder I copied it into is empty. The file was a 700mb movie, which I copied into my videos. After the transfer was complete, my videos was empty but my documents had an extra 700mb added to its size. My hard drive showed a 700mb chunk of space missing from it as well. I know the file was copied, but there is no icon anywhere to show its location. Has anyone experienced this before?
