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 (ODP, ODS
and ODT), iWork (KEY, PAGES, NUMBERS), and Capture One Enhanced Image
Package (EIP). The ExifTool family 3 groups may be used to organize the
output by embedded document number (ie. the exiftool -g3 option).
