I´ve totally lost the name of it. The idea as to be able to send/handle a Mac file in an alien system without stripping the RF.
The program was in two parts: one de-forking the file and one re-forking the file, thus sending the RF and DF as two separate files. I´m convinced it was a Classic-only app, maybe even earlier than OS 9.
Anyone knows what I´m on about?
