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.
