What is a KEY file?

A KEY file is a presentation document created by Apple Keynote, part of the iWork productivity suite. Technically, the format has evolved through two primary iterations: a package directory (bundle) containing XML data and media assets (Keynote '09), and a single-file Zipped archive using Protocol Buffers (Protobuf) for efficient serialization (Keynote 2013 onwards). It utilizes a proprietary schema to store slide geometry, animations, and media, distinct from the Office Open XML standard.

How to open a KEY file

Native access is exclusive to macOS, iOS, and iPadOS devices via the Apple Keynote application. Users on Windows or Linux can view and edit these files via iCloud Keynote in a web browser. Conversion to PDF or PPTX is often required for offline viewing on non-Apple systems. LibreOffice offers limited import capabilities for older version 09 files but struggles with modern Protobuf-based KEY files.

What is a POTM file?

The POTM format is a macro-enabled presentation template introduced with Microsoft Office 2007, adhering to the Office Open XML (OOXML) standard. It utilizes ZIP compression to organize XML components but, unlike standard POTX files, allows the storage of Visual Basic for Applications (VBA) code within a vbaProject.bin part. This distinction enables the automation of tasks and custom scripting within the template structure.

How to open a POTM file

Opening POTM files requires software capable of executing or suppressing VBA macros securely. Microsoft PowerPoint is the primary application for Windows and macOS. While LibreOffice Impress and WPS Office can open the slide content, macro execution may be restricted or unsupported due to differences in the scripting backend compared to the Microsoft VBA engine.
