Como Descargar Un Audio De Messenger

I've got a document I created back in 1990 using a wp program, Adobe pagemaker. it's about 275 kb long, which is tiny by today's standards. I would really like to be able to open this thing, but I can't find a translator anywhere that will do it. The window on my desktop shows the file has an exec designation at the top left hand side of the file, so I'm guessing that's a formatting style or something.
