Opening PPSX files
Did your computer fail to open a PPSX file? We explain what PPSX files are and recommend software that we know can open or convert your PPSX files.
What is a PPSX file?
The .ppsx file extension is used by the Microsoft PowerPoint presentation software. PowerPoint allows users to create slide shows containing images, text, music and video. The PPSX file format is used for versions of PowerPoint 2007 and later. Versions prior to the 2007 edition of the software were assigned the .pps file extension.
The new "x" that has been assigned to the file extension in the later versions of PowerPoint stands for "XML". The XML file format was introduced with the 2007 version of PowerPoint. The XML technology allows for better data management and data recovery of PowerPoint files.
Software that will open, convert or fix PPSX files
Try a universal file viewer
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
