Audibook in Music File

I really hope someone will help me with this. So… I was trying to put the txt on my mp 3 player. At first, I conected my USB to my computer, then I open the file, and saved my notpad on the audiobook, but after I unplugged it, on my mp3 player, it says that my audiobook file is empty. So can anyone help me with this? Thank you.

Is the file a .txt file?  That type of file is not supported by the Clip.  While you can store a .txt file on the Clip, the Clip cannot open or read it.
