Hope Mark is still following this thread.

What are the rules for the naming of these subdirs?

I can see that fidsift.sh chops the fid into directory and file components, but is this the required modus operandi?

Reason I ask is that I'm looking into creating my own local 'fids' structure that I can then simply rsync up to the empeg (sadly mp3tofid is not quite suitable for my requirements) and so I can create whatever directory structure I want.

Can the subdirs be any name, or do they have to be in the format that Mark creates with fidsift? I guess it's dependent on how the player searches for files and about that I have no idea.

How many levels of subdirs can there be? I assume only this one, but have to ask.

Ta.
