would like to open up this again with a kinda related topic to serialisation. file identification. looking to find a simple way to manage files that are linked in other files, in this case samples that are used in sequencer patterns, and similarly patterns used in compositions. could creating some kind of hash tables be a good start? or maybe a simple route with just file name comparison goes a long way? and I should probably add that this is for files saved on fat32/memory cards, just beginning to read up on fat and fat directories, still stumblin' unfortunately.
