Can't Drag Files to MP3 Player or other HD
 

Help !! For some reason I can't drag the finished downloads (they are in my User-Shared Folder)
to another MASTER MP3 FOLDER Thats' on another Hard Drive. I get an error message each time I try (error -50) I like to back up all of my MP3's on an external HD that is there JUst for MP3's .. I've never had this problem before. Now I can't drag them to the icon of my MP3 Player either ??
Using 10.2.8
