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.
