The path name must begin with a slash (/). The path is made up of the file system name, the volume name, the directory and subdirectory names, and the file name.
- For example:
/QOPT/VOLUMENAME/DIRECTORYNAME/SUBDIRECTORYNAME/FILENAME
- The file system name, QOPT, is required.
- The volume and path name length vary by optical media format.
- You can specify /QOPT in the path name or include one or more directories or subdirectories in the path name. Directory and file names allow any character except X'00' through X'3F', X'FF'. Additional restrictions may apply based on the optical media format.
- The file name is the last element in the path name. The file name length is limited by the directory name length in the path.
For more details on path name rules in the QOPT file system, see
