Not odd at all since the files in question are MP3. Depending of which app is started determines what files will be recognised by the device. The same holds true for pictures.
So if you start poking around in the wrong folder you run the possibility of thinking there is nothing in the folder just because the file is not recognized by the active app.
Some of you already know this but an mp3 is an audio file. It doesn't care whether the source is a song or the spoken word. It's just a format. So just because it is an audio file of someone(s) reading a book doesn't mean that the book reader app recognizes it.
When reading a book and you decide to listen to background music by turning on the option via the option menu you are basically starting up another app that is running in the background.
The same holds true for pictures. The unit supports multiple picture formats such as jpeg, gif etc. These can only be viewed via the picture viewer app or in some circumstances as part of a document such as when viewing HTML documents. The picture files will be called into view from a specified folder as required when reading the document. Some documents do not support embedded pictures such as txt formated documents.
Unlike the Libre the jetBook has 4 options on it's front menu - "Books", "Audio Books", "Pictures" and "Settings". The "Audio Books" option is really just a basic mp3 player app. It pulls up all audio files found in internal memory or on the SD card.
