Hm. Not sure, I haven't ever done that.

But I do know that the MP3 files are just more files like the FID index files. The index file is the one ending in the number "1" and the actual data is the file ending in the number "0". For instance, on my player, the actual MP3 file of Tom Sawyer is "/drive0/fids/bf90" and the song's index/tag data is stored in "/drive0/fids/bf91".

The files that end in "1" are just ascii data containing the song or playlist information. For instance, on my player, /drive0/fids/bf91 looks like this:

duration=273946
bitrate=fs256
genre=Progressive Rock
file_id=01
type=tune
length=8767903
codec=mp3
artist=Rush
offset=1627
tracknr=1
ctime=1053562286
year=1981
source=Moving Pictures
rid=70d3fc79d7338bd1c897ebeae124d987
samplerate=44100
title=Tom Sawyer

(from what is a fid?)

I would have figured that the purpose of MP3toFID was to do that particular processing on everything for you. I guess not?
