what folder for MP3 audiobooks

I have some audiobooks that are actually just many MP3 files that I ripped from CD audiobooks.  What folder do I put the audiobooks in.  I see 2 folders on the Clip Sport: Music and Podcasts, but I don’t see an Audiobooks folder like on the Clip Zip.

The folder is there now!   It just appeared.

Did this take time to refresh? If I may ask, how many hours did it take for your case?
