# V ZIP File Media (Normative)

## V.1 DICOM Mapping to ZIP File

### V.1.1 DICOM File-set

One and only one DICOM File-set shall be contained in a ZIP File archive.

Each DICOM SOP Instance shall be encoded in accordance with the rules in PS3.10.

### Note

A ZIP File may contain files that are not referenced by the DICOMDIR, which may be ignored by the DICOM application.

### V.1.2 DICOM File ID Mapping

The ZIP encoding preserves the hierarchical structure for directories and files within directories. Each volume has a root directory that may contain references to both files and sub-directories. Sub-directories may contain reference to both files and other sub-directories.

#### V.1.2.1 File ID

PS3.10 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 file names 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 path name in a ZIP file-set shall be at most 8 levels, to comply with the definition of a DICOM File-set in PS3.10.

#### V.1.2.2 DICOMDIR

One and only one DICOMDIR File shall be present. The DICOMDIR shall be at the root directory of the File-set.

### Note

The reason for the DICOMDIR is to serve as a manifest so that the recipient knows the full list of instances intended to be sent.
