Hi,
Apple and MS call this feature, multiple streams file, so could use that
name too :-) Apple did it first, and MS copy it (actually, improved it a
lot.) and MS does use it, never wonder where the author field from each file
came from? Anyway, you can generate and open each stream as a separated
file, if you want to read foo, stream bar, just open foo::bar.
