Abstract: A housing system for storing a disk container is disclosed. Two panels are connected by a hinge web so as to form a clamshell type housing. Hooks are removably connectable to a panel so that the system can be converted from a housing usable with ring binder type notebooks to a system usable in upright file cabinet storage. There is also provided tabs and holes for retaining the disk containers in place and assisting in their removal, a label holder, a display window suitable for displaying identifying information for the disk, and a rectangular well suitable for receiving documentation for the disk opposite the recess.
