V.1.2.1 File ID

PS 3.10 defines a DICOM File ID Component as a string of 8 characters from a subset of the G0 repertoire of ISO 8859.

Note: The use of long filenames is prohibited.

Filename extensions are not used in DICOM File ID Components, hence a File Identifier shall not contain a File Extension or the '.' that would precede such a File Extension.

The maximum number of levels of a pathname in a ZIP file-set shall be at most 8 levels, to comply with the definition of a DICOM File-set in PS 3.10.
