Audiobooks not playing in order

In my experience the Clip Sport doesn’t sort numbers in a desired way. I therefore use the utility FATsort to sort the files in “natural order” and then the folder view in the player to access the content. The player itself sort the files in alphanumeric order which is kind of useless for many audiobooks. Some examples:

Natural order:

file3.mp3

file21.mp3

file123.mp3.

Alphanumeric order:

file123.mp3

file21.mp3

file3.mp3

The Clip Sport use the Alphanumeric order in database view. Personally, I can’t come up with any examples of when this is desired for Audiobooks (which often contains of many small numbered files) but don’t expect this to change. The Clip+ and Clip Zip use the natural order though.
