Improved block folder that comes constituted by two lids articulated to each other through an intermediate spine, in which internally other retention organs are arranged for sheets of paper, is essentially characterized in that one of the aforementioned covers externally, presents a pocket, constituted by the lid itself and by a rigid sheet of larger dimensions to which said lid is joined by means of a flexible and folding laminar band as a bellows, it being provided that said rigid sheet can serve on its external face, as a support of books, or similar organs, which will be held over it by appropriate means.
