Opening PPTX files

Did your computer fail to open a PPTX file? We explain what PPTX files are and recommend software that we know can open or convert your PPTX files.

What is a PPTX file?

The PPTX file extension is given to Microsoft Power Point files that are created in PowerPoint versions 2007 and later. Microsoft PowerPoint is a presentation software that allows users to create slide shows containing pictures, text, music and video. The PowerPoint program is included in the Microsoft Office Suite.

Earlier versions of Microsoft PowerPoint create files using the .ppt extension. The .pptx extension is being assigned by later versions of PowerPoint because these versions of the software use the Open XML format. This format allows PowerPoint files to be compressed into smaller sizes, making it easier to distribute the files online and taking up less drive space on a user's computer.

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.
