ZIP Tags
The following tags are extracted from ZIP archives. ExifTool also extracts
additional meta information from compressed documents inside some ZIP-based
files such Office Open XML (DOCX, PPTX and XLSX), Open Document (ODB, ODC,
ODF, ODG, ODI, ODP, ODS and ODT), iWork (KEY, PAGES, NUMBERS), Capture One
Enhanced Image Package (EIP), Adobe InDesign Markup Language (IDML),
Electronic Publication (EPUB), and Sketch design files (SKETCH). The
ExifTool family 3 groups may be used to organize ZIP tags by embedded
document number (ie. the exiftool -g3 option).
