The present invention relates an improved structure of a file which can stand in an upright position comprising (a) an outer covering board having a horizontal scored line across the center of the board so that the outer covering board is bendable outward along the scored line; (b) an inner covering board positioned at the side of the outer covering opposite to the direction of the outer covering being bent, and being mounted with a document clipping device; and (c) two thin boards mounted perpendicularly from the bottom edge of the outer covering board, proximate to the lower corners, to the bottom edge of the inner covering board, proximate to the bottom corners of the inner board, wherein the center of the thin boards are provided with a bending section, thereby when the lower section of the outer covering board is extended or bended outward and the two thin boards are fully extended, the file stands upright on a flat surface, and when the lower section of the outer covering board is retracted towards the inner covering board by bending the thin boards at the bending section, the file is folded for storage.
