Loaded SF files have no samples attached

Re-entering this field after a long absence.

I load a soundfont file into Polyphone and in the Samples area there are no....samples. If I save or export the file, it is unusable by any SF(x) player, because of the lack of samples.

IIRC sometimes the samples were stored in the same folder (or sub-folder) as the SF file itself, and I think that is the problem here.

My problem (well at least as regards this particular issue :( ) is that I am trying to modify Cakewalk SF(x) files, because the synths in CW do not allow me to do "stuff" that I may want to, or they are very cumbersome to set up each time. The file layouts do not seem to make it easy to associate the SF file with its samples...perhaps deliberately?

Is there a way to find out where the samples for a SF file are located, perhaps by investigation of the SF?

EDIT: I have actually found some samples by digging about in folders until I got lucky. But if there is a better way I would still like to hear.

Thanks for any help.
