Recovering held optical files

 

A held optical file is an optical file that could not be closed normally. This topic provides information on recovering held optical files. The file contains buffered data that cannot be written to the optical disk. If the open file handle is still valid, the file is still open; otherwise, it is considered closed. Held optical files are only created for media format *HPOFS when the Change Optical Attributes (CHGOPTA) Held file attribute field is *YES. Held optical files are not created for media format *UDF or when the Held file attribute field for the CHGOPTA command is *NO.

• How optical files are used
  An application can manipulate optical file data by using UNIX-type APIs or the hierarchical file system (HFS).
