How the File System Manages Information
The file system is the part of the MPE/iX operating system that manages
information being stored or transferred. It handles various input/output
operations, such as passing information to and from user processes. All
input and output operations are done through files. Files can be kept in
any storage medium and accessed by any input/output peripheral device.
Two basic types of files exist:
* Disk files. These are files residing on disk, immediately
accessible to the system and potentially shareable by several
sessions or jobs at the same time.
* Device files. These are files currently being input from or
output to any peripheral device except a disk.
