Hi A file is nota E73 information object. It is a physical object. You may store your portrait of Martin on a punch tape (of a considerable length) or a stack of punch cards for that matter. In principle there is no difference between an object with a magnetic emulsion and a punch tape with respect to carrying information.
Yu ma also go back to the polyphone (http://www.hlxx.de/hp/polyphon.htm) which indeed by many have been considered to be a heap of scrap metal and pieces of wood. Still it is able to store information.
