Section C.38.2.2.1.2
C.38.2.2.1.2 Filename in Container, File Offset in Container, and File Length in Container
If the stored SOP Instance is included in a ZIP, TAR, or TARGZIP container file as specified in Section P.1.2, Filename in Container (0008,040B) is the filename within that container file of the file containing the SOP Instance.
If the stored SOP Instance is included in a BLOB container file, and optionally for other container formats, File Offset in Container (0008,040C) is the byte offset for the start of the file for the SOP Instance, and File Length in Container (0008,040D) is the file length. For TARGZIP container files, this is the offset within the TAR container file after extraction from the GZIP container file.
Note
Locating a file by filename within a container file may require parsing the entire container file (TAR) or look up in the index (ZIP). The File Offset in Container (0008,040C) and File Length in Container (0008,040D), if provided by the SCP, allows the SCU to directly access a specific file.
