A rack mounted inside a cabinet in which a number of office files are supported, wherein the rack can be extended outward of the cabinet allowing all of the files to be visibly seen for easy identification along with the easy removal of any file. The files are supported one above the other so that each file tab is higher than the lower one.The rack is shaped to fit inside a cabinet that is substantially as tall and as wide as a conventional filing cabinet but is thinner and capable of being wall mounted and thereby consuming a minimum amount of floor space.
