how do I get 2-digit chapter numbers?

I see it's an option to set the number of digits for the series title in the folder structure. How do I set the number of digits for the chapter number for the converted audio files themselves? I need the files to be in dumb alpha order for my mp3 player, so I rename "chapter 1" to "chapter 01" etc by hand after the conversion. Thanks!

Two options here:

• Use the playlist (.m3u) to play the book. The playlist has all tracks in correct order, independent of their name and folder structure.
• If your favourite audio player does not support playlists, you can add a numeric prefix with the correct number of digits to each audio file name. Go to Basic Settings, select the Chapters tab, and in Use name chapters select Yes, always precede with number.

Thanks. I didn't know about the "Yes, always precede with number" options. That did the track.
