Really? What is the purpose to enumerate all used files in the LV2 session? Because from sampler perspective, only the "main" instrument file name has to be passed when loading a session. The sampler (or in this case libgig) will then automatically detect and retrieve the list of extension files from the main gig file and load the extension files automatically. Anyway, if you really need to enumerate all files, tell me, then I will patch libgig for this task. > > > > (That 32-bit limit really sucks...) > > > > Not thaaat bad. ;-) The workaround with extension files is a bit ugly, > > but it works on all systems.

If its a custom application you can also just use 64 bit RIFF chunk offsets instead of 32 bit ones of the original RIFF format and that's it. Some people also did it like this: they placed all RIFF chunks into the first 2 GB of the file, and e.g. placed their huge audio sample data after all those RIFF chunks and used 64 bit file offsets to reference the sample data from RIFF chunks. However Tascam decided not to do that for the Gig format, in favor of the extension files solution, because there are many systems which still have a 2 GB file size limit in general.
