DescriptionPPTX is an extension for the storage of slideshows and presentations for PowerPoint 2007 and the latest editions. It is created with audiovisual details, a set of slides, multimedia objects, and formatting. The XML format was used to create the file, enabling users to view the recorded information in text editors.
Technical detailsThis file is created to be unique, with its specifications contained in the ECMA-376 standard for Office Open XML. PPTX file can be made by zipping up a directory. However, the directory contents must be the same as an OPC structure with subfolders having the contents in XML format. Any application that is compatible with XML can use data in the new file format. Also, the PPTX file is similar to the DOCX file format as it improves data recovery and data and file management.
