Directory Differences
HP-UX provides an n-level hierarchical directory structure, where a fully
qualified file name is identified by its path from the root directory,
for example:
/dirname/dirname/dirname/filename
[REV BEG]
The traditional MPE/iX file system provides a three level directory
structure. A fully qualified file name is identified by the group and
account where it is located, for example:
filename.groupname.accountname
After Release 4.5, the file system structure of MPE/iX is enhanced with
the introduction of the MPE/iX hierarchical file system (HFS). In this
structure, MPE/iX accounts and groups are considered to be special
directories that serve as hierarchical directories while continuing to
serve as traditional MPE accounts and groups. Like HP-UX, MPE/iX can now
have an n-level hierarchical directory structure. Thus, there is no need
to change any references to include files or other files in your
application.
Directory names have the limitation that only 16 mixed case characters
are allowed if the directory exists under the root directory or directly
under an MPE group. Elsewhere, up to 255 characters are allowed.[REV
