IMPROVEMENTS IN DOCUMENT FILING FOLDERS, characterized in that they essentially consist of practicing on one of the largest longitudinal margins of a cardboard sheet of rectangular shape, three folds folded in the opposite direction and successively alternated, performing at the edge of the second fold, a slot through which a clip that is occluded inside a double bottom fold slides rectilinearly inwards or outwards and in a perpendicular direction; in such a way that when penetrating inward, the outer tongue overlaps and penetrates through the lower fold of the flange, while the base of the clip is in the lower fold of the sheet, pressing against each other and retaining the documents interposed between both.
