The FSC shall be able to create a DICOMDIR File containing the Media Storage Directory SOP Class for the created File-set and create zero or more Files belonging to the File-set by invoking M-WRITE Operations with SOP Instances that meet the requirements of the corresponding IOD. It is the responsibility of the FSC to ensure that the M-WRITE results in the creation of a correctly formatted DICOM File. The manner in which this is achieved is beyond the scope of the DICOM Standard.

The FSC shall support the Media Storage Operation M-INQUIRE FILE-SET and may optionally support the M-INQUIRE FILE.
