A foldable file, essentially consisting of a box or sheath constituted by a sheet of cardboard conveniently folded by fold lines that determine the longitudinal edges of a rectangular prism and a base determined by prolongations of the faces of the prism, two of which corresponding the wide faces have means for holding them, consisting of an eye and an extension or flange. A second element as a drawer or file itself, consisting of a sheet of cardboard square, with two fold lines that determine the sides and the bottom, continuing said laterals in separate extensions as inverted trapezoids, the largest base of one of which is prolonged, in a rectangular piece of the same dimensions as the bottom of the drawer, on which it is refuted, reinforcing it, while the other trapeze extends into another flange, which conveniently folded is arranged under the false bottom determined by the aforementioned rectangular piece. The front and rear ends are constituted by two rectangular pieces joined to the bottom of the drawer by a flange, these pieces being bent by their midline on themselves, thus remaining double thickness and extremely resistant. A small flange on the edge that is inserted under the false bottom of the drawer and some lateral fins, which are attached to the side faces of it, reinforce the whole.
