Description🔵 The KEY file extension is used for Keynote Presentations. This software was created by Apple for creating and playing presentations. 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. The new version of Keynote saves a file with an "index" directory in Apple's proprietary IWA file format, a "Metadata" directory with .plist files, a "Data" directory with image assets such as backgrounds and photos for slides, and jpg files for previewing. Keynote files in iWork can only be opened using iWork.
