PPSX, PowerPoint Open XML Slide Show (.ppsx)

The PPSX Presentation file format

PPSX is a PowerPoint Open XML Slide Show which was mainly designed to be non-editable and basically playback a PowerPoint presentation created prior. Files with the PPSX extension differ from PPTX which permits the file to be editable. The “X” extension refers to Microsoft Office 2007, 2010 and 2012 which ZIP compresse the file. Therefore, PPSX filles are different from the older versions that generally have files with large sizes.

Technical details of PPSX files

PPSX are the compressed files that are based on the ECMA 376 standard for Office Open XML. Video, audio, image and text files can be supported by files with this extension. PPSX files are stored in a zipped directory format that matches the OPC structure. Like the PPTX format, the PPSX file format improves data recovery, data management, and file sizing. It permits for other applications to interact with it due to the XML structure.
