Abstract: A one-piece file folder is provided with an integral tab structure. The preferred file folder broadly includes a paperboard body formed into a plurality of panels hingedly connected by a fold line. The panels are folded along the fold line and secured to form an assembled file folder. The file folder also includes an integral tab structure cut from one of the panels which presents a fold line common to the paperboard body fold line. The tab structure pivots about the fold line so that it either extends from the assembled file folder or lies flat relative to the assembled file folder.
