A file in the. pptx format is a file generated by power point in versions above Office 2007.

The following versions of Office 2007 do not open files of this format. If you want to open the file in this format, the easiest way is to download a PPT viewer software that can be opened directly after installation. Make a few notes: PPTX is the default format for Microsoft Office PowerPoint 2007 and Microsoft Office PowerPoint 2010, with Microsoft Office PowerPoint Version 2007 is available and can be opened with Microsoft Office PowerPoint 2003 to install a Compatibility pack. Of course it may be easy to install a compatible package, but I haven't tried it. I suggest you install the PPT Viewer, the software is not very large and easy to operate.
