A filing system used in business for secure and ordered storage of files. Consists of a number of large steel cabinets mounted on toothed railings on the floor. When "closed", the cabinets are placed end to end to present a low-profile exterior and take up less space. On the outside of each cabinet is a round handle to open the entire assembly in the middle, at the appropriate cabinet. Allows many files to be stored closely packed, and also allow easy access to any point in the filing system without requiring "dead" space for access.
