6.2.1 Requirements

  • Keep and maintain a list of all user filenames created from host
  • Full list of all system and configuration filenames is required. For more information, see Section 5.
  • If allocated, size per file is also required:
    • Keep and maintain for each user file its allocated size (either the size of the content or the maximum size argument)
    • Full list of all system and configuration file sizes is required. For more information, see Section 5.
  • Knowledge of how to accurately calculate the occupied memory space per file. For more information, see Section 4.
