Abstract: The folder is made with a pair of sections, each of which is provided with an inside panel to form a pocket. The inside panel and the front panel of each section of the folder is provided with vertical and horizontal score lines adjacent the respective edges of the folder to permit expansion of the pockets when filled with paper or the like. The folder is also provided with a pair of score lines on opposite sides of the vertical fold line to allow the folder to triangulate along the vertical fold line when the folder is filled to capacity. When filled to capacity, the folder retains a flat appearance.
