Abstract
Abstract A file holder including an outer casing defined by a plurality of panels and a cover serially and hingedly connected to each other. Further, the file holder includes a file assembly having a plurality of compressible envelopes sequentially joined together, wherein a first end of the file assembly is joined to a front panel, and a second end of the file assembly is joined to a movable board. The file holder is cooperable between closed and open positions. In the closed position, the outer casing encloses the file assembly, and is secured via an engaging device. In the open position, two of the panels extend coplanar and away from the front panel, while the cover is rotated upwards and secured to the movable plate via a securing device to provide relatively rigid structure for the file assembly.
