PPSX file refers to PowerPoint Open XML Slide Show. It is the proprietary file extension created by Microsoft Office PowerPoint 2007. The biggest drawback behind these files is that they are non-editable and can only be used as PPT playback.
But, if you liked a .ppsx file and you would like to save some slides or edit some information in the slides, what do you do? Well, there’s an easy solution.
Start Microsoft Office Powerpoint 2007, click on the start button and open the .ppsx file. You can edit the file easily now. And, to convert a ppsx to ppt or pptx, simply save the file as .PPT or .PPTX. Pretty simple isn’t it?
Well, this was a query by one of my friends. To my surprise I too wasn’t aware of the solution but I never thought it would be as simple as I mentioned.
