I have just recently bought a c240. The USB mode is sset to MSC so I can drag and drop songs into it. It doesnt let me put in anymore than 116-118 songs before I receive an error: “Cannot copy (file name), the file or folder could not be created”. the memory isnt an issue, I have well over 300 MB of free memory left. And it doesnt matter which specific songs I put onto it, I cannot go over 116-118 songs. They’re all MP3 fomat.
585/959 MB used
