Description As part of Microsoft's 2007 suite another open XML document type was introduced.

Technical Details A PPTX file is quite unique. The specifications for PPTX are in the ECMA-376 standard for Office Open XML. You can make a PPTX file by zipping up a directory, but the material in the directory has to match an OPC structure, including subfolders that have the content in XML format. Any application that supports XML can access and work with data in the new file format. Just like the DOCX file format, PPTX improves file and data management and data recovery.

key09 KEY09 (Document)

File extension .key09
Category Document File
Description Files with a .key09 file extension are presentation documents which are generated by Apple's "Keynote" application in versions 5.0, 5.1, 5.2 and 5.3 (these versions of the software were released between 2009-2012).

This is distinct from the key file produced by more modern versions of iWork.

Keynote is one of 3 programs which make up Apple's iWork office suite, a set of applications which run on the Mac OS X and iOS operating systems, also including Numbers (for spreadsheets) and Pages (for word processing).

Keynote was first released by Apple in January 2003 and began life as a program used by Steve Jobs when creating presentations for the MacWorld Conference and Expo.

Technical Details Official file format specifications for iWork '09 Keynote files are not published by Apple but there have been attempts by some developers to reverse engineer them. At the top level iWork '09 Keynote files represent a zip file containing:
  1. An index.xml file
  2. A buildVersionHistory file
  3. A "QuickLook" directory with a "Thumbnail.jpg" of the document. The directory may also contain a PDF file named "Preview.pdf" if the user chose to save the original document with additional preview information in Keynote.
The index.xml is the core component of the file, containing the document content and all of the metadata for formatting it. This XML is not standards-based as Keynote does not support the OpenDocument file format used by Microsoft.

Files created by Keynote in iWork '09 are not backwards compatibile with earlier versions of iWork. Keynote files cannot be opened by programs other than iWork.
