Optical file system (QOPT)

The QOPT file system provides access to stream data that is stored on optical media.

• Integrated file system and HFS in the QOPT file system
  Operations can be performed on objects in the QOPT file system through either the integrated file system interface or APIs provided by a hierarchical file system (HFS).
• Case-sensitivity in the QOPT file system
  Depending on the format of the optical media, case may or may not be preserved when creating files or directories in QOPT. However, file and directory searches are case-insensitive regardless of the optical media format.
• Path names in the QOPT file system
  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.
• Links in the QOPT file system
  The QOPT file system supports only one link to an object. Symbolic links cannot be created or stored in QOPT.
• Use integrated file system commands and displays in the QOPT file system
  Many integrated file system commands and displays are valid in the QOPT file system.
• Use integrated file system APIs in the QOPT file system
  Many integrated file system APIs are valid in the QOPT file system.
