Abstract: A file folder assembly is easy to construct and utilize, is simple to expand, and allows a maximum number of discrete files to be stored in a minimum amount of usable space. First and second slotted shelving uprights extend generally parallel to each other and are mounted on an office panel or wall. Pairs of side brackets with mounting ears and lock projections fit within the slots, and have rod receiving openings at opposite ends. Rods, e.g. round galvanized steel rods, pass through collars formed at the ends of flexible file folders, each rod gripped by the side brackets at opposite ends, two side brackets supporting two rods and the flexible file folder extending between them. The file folder may be of polypropylene or PVC sheet material, creased at a lower portion so as to prevent papers disposed in the file folder from rising up the sides.
