I.2.2 Behavior of an FSR

The FSR shall be able to recognize a File-set and the corresponding DICOMDIR containing the Media Storage Directory SOP Class. A valid File-set may contain only a DICOMDIR and no other files. If a File-set contains other files with stored SOP Instance, the FSR shall be capable of invoking M-READ Operations to access the content of the Files of the File-set. The manner in which this is achieved is beyond the scope of the DICOM Standard.

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