Information about PPSX and PPT file formats

🔸 File format PPSX PPT
🔸 Full name PowerPoint Open XML Slide Show PPT - Microsoft PowerPoint Binary File Format
🔸 File extension .ppsx .ppt
🔸 MIME type application/vnd.openxmlformats-officedocument.presentationml.presentation application/vnd.ms-powerpoint
🔸 Developed by Microsoft Microsoft
🔸 Type of format Document File Presentation
🔸 Description PPSX is a PowerPoint Open XML Slide Show - it is primarily designed to be non-editable and simply playback the Powerpoint presentation. It differs from PPTX, which allows for the file to be editable. The 'X' extension refers to Microsoft Office 2007, 2010, and 2012 which ZIP compresses the file and is therefore different from the previous versions, which generally have larger file sizes. Microsoft PowerPoint up until 2007 version used a proprietary binary file format called PowerPoint Binary File Format (.PPT) as its primary format. In Microsoft Office 2007, the new XML-based Office Open XML formats replaced the binary file formats as the default format.
🔸 Technical details PPSX are compressed and based on the ECMA-376 standard for Office Open XML. It supports Text, Images, Audio, and Video and is stored in a zipped directory format that matches the OPC structure. Like the PPTX format, the PPSX format improves file sizing, data recovery, and data management and allows other applications to interact with it due to the XML structure. The binary format specification has been available from Microsoft on request, but since February 2008, the .ppt format specification can be freely downloaded.
