When I began to drive my CRV I put some MP3 files on a USB stick, under a bunch of folders by the album.
This worked fine, and during the playback the stereo displayed and played them back in the alphabetical order of the folder names.
Later, I added more folders with MP3s to the stick, and all hell broke loose: nothing was in the alphabetical order anymore.
I tried to Linux 'touch' the files, to eliminate the possibility that the stereo uses the file date/time, but it changed nothing at all.
Is there any way to restore the alphabetical order of the folders on screen and during the playback?

 

Write the files to a hard drive or something. Format the stick and copy the files back on to it.

 

This implies that I have to fiddle with each and every stick. Not really looking for such solution.
