I have emc 10. I am trying to backup up my pictures to a DVD in there folders. I can get the pictures backup on my 4.7GB DVD but when I go to view the pictures, I have added thumbnails that I did not add. They are album.pvm,mpvthump, and highmat. How did they get in the projet since I did not add them? I what to back up my pictures so if my harddrive fails I can restore the pictures back. Is creator classic the best way to backup my pictures?
