A file folder has a front and a back cover which are joined together so as to allow the folder to open and close. Each cover has a pocket mounted at its outer lateral end position. Inner sheets are secured at one lateral edge of each to the inner line thereof to form tiered pockets which are opened at their upper, lower and outer lateral ends. The covers are provided with apertures at their inner lateral end portions so that the folder may be mounted in a conventional two or three ring loose leaf binder.
