Quick Link: .ZIP Application Note

.ZIP Application Note

PKWARE® introduced the ZIP format in 1989. This new format combined data compression, file management, and data encryption within a portable archive format. ZIP quickly became the accepted industry standard for cross-platform data exchange and efficient data storage. In order to ensure the continued interoperability of the .ZIP file format for all users, PKWARE publishes an Application Note on the .ZIP file format. The APPNOTE provides developers a general description and technical details of the .ZIP specification. This specification is maintained and periodically updated by PKWARE with support from interested industry experts and other users of this format. These changes are intended to include new capabilities in anticipation of the emerging needs of the ZIP community, while ensuring on-going interoperability for ZIP files.
