What is a .ppsx file?
File extension details and usage information
A PPSX file is a Microsoft PowerPoint Slide Show file created using the Office Open XML format. It was introduced with Microsoft Office 2007 to replace the older binary PPS format. The primary distinction between a PPSX file and a standard PPTX file is how the application handles the file upon opening. While a PPTX file opens in the editing or 'backstage' view, a PPSX file is designed to launch directly into the full-screen slide show presentation mode. This makes it an ideal format for distributing finished presentations to audiences who do not need to edit the content, providing a professional and seamless viewing experience from the moment the file is opened. Under the hood, a PPSX file is actually a compressed ZIP archive containing various XML files that define the presentation's structure, text, formatting, and references to embedded media like images and videos. Although it opens in presentation mode by default, users can still edit a PPSX file by opening Microsoft PowerPoint first and then using the 'Open' command to browse for and select the file.
