A workaround is to use the software Mp3tag and change the ID3 tag for Title and Track for all the files. Make sure the total length of the title don’t exceed 12 characters. Each title should be numbered. An example:
Title field: Chapter 1
Track field: 1
Tittle field: Chapter 2
Track field: 2
Title field: Chapter 3
Track field: 3
If you have a file with the title “In the shadow of darkness 110” and track number 110 the title will be truncated on the sport and not sorted correctly. The title “darkness 110” will, however, work. It might seem like a daunting task but Mp3tag makes it easy to update all the files at once: http://www.mp3tag.de/en/
Another workaround (if you are a Mac or Linux user) is to use the FATsort utility (command line only) and sort the files on the player in “natural order” (-n) and then the folder view on the player to access the content.
A third workaround is to create a playlist with the files in proper order.

I know these are just workarounds but due to its hardware limitations I don’t think the behavior of this player will change.
