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), 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).
