This invention provides for an essentially open file folder construction where the containment means allows for use of the file folder in an open style as featured in all file folders, while at the same time providing for a box like closure structure that allows for closure along the spine and orthogonal bottom edge of the file folder, which locking closure has the additional feature of showing a substantial portion of the contents, enabling a self typing categorization of the folder by way of the meaning first member contained therein, which member is partially viewable when said file folder is set into its locked configuration. The primary basis for offering the locking feature is by way of a retaining panel along a bottom portion of the back panel with a leading edge substantially at or partially offset from a hinged front panel such that the hinged front panel, when folded backward and into the file folder may be latched behind the retaining panel to lock the front panel in a half open position, thereby forming a containment system, with no other supports for closure than the locking front panel and retaining flap.
