DISK/DIRECTORY SYSTEM

The disk/directory system provided the user machine. (The ECS system was merely intended as a tool for the production of the disk/directory system.) Further levels above the disk/directory system were thought of more in terms of executives than artificial machines. Objects that existed in the disk/directory system were called disk objects, of which the two major ones were files and directories. The files provided a place to store data much as in the ECS system and the directories provided a naming structure for the disk objects. Also, the directories stored disk level capabilities, corresponding to the function provided by C-lists in the ECS system. A number of other disk objects existed and will be described subsequently.
