Development of Norton Commander

Norton Commander was an influential DOS-era file manager originally developed by John Socha, with its first version released in 1986, followed by several major upgrades through version 5.5 (1998). The software achieved cult-like popularity, particularly in Eastern Europe and the former USSR, where it became synonymous with the DOS interface itself, and spawned numerous Orthodox File Manager (OFM) descendants that continue to exist across modern operating systems.
