I have a very strange problem. I have recently experienced that MP3 files and JPEG files disappear when I edit them. I have for example rotated a JPEG image in the Windows photo viewer and changed the album name on an MP3 file in windows media player. After this I can no longer find the file in the folder. The MP3 file can still play in windows media player but in the folder where the files used to be it says "folder is empty". What is going on? I do not understand it! Hope someone can help me!
