Keynote presentations are stored in the Mac OS X package. These files contain all the necessary elements for a presentation, such as slides, images, transition information, and text. Additionally, KEY files can store XML data used for presentations. Introduced in 2003, Keynote was developed as a competitor to PowerPoint.
Technical details	🔵 Specifications for Keynote files are not available, but one can refer to the iWork '05 file format by Apple. The .key file is a compressed ZIP file that contains other files necessary for the presentation.

Keynote files in iWork can only be opened using iWork.
