Michigan Terminal System (MTS) is an operating system for the IBM System/360 and its successors that was developed jointly by the following institutions:

Popular programs developed for MTS include MAD (programming language), Micro DBMS, an early relational database management system, the FORMAT text formatting system, and the CONFER conferencing system from Robert Parnes.

MTS doesn't implement directories, but there is a de facto two-tier grouping of files owing to the inclusion in a file's name of its owner's four-character MTS callsign.
