A .PPSX file represents a presentation file format saved in the PowerPoint Open XML file format. The Open XML file format enhances the readability factor of the presentation content when accessed through other programs, such as OpenOffice.org, free PowerPoint Viewer program. While the PPSX file is created through the Microsoft PowerPoint program, the PPSX file once saved cannot be edited. Hence, the PPSX file is used for sharing the completed presentation slides which can be viewed through the free PowerPoint Viewer program.
When you install one of the applications from the list of programs that you found here, you should be able to open or edit the file with the PPSX extension without any issue. However, if you still have problems with this, you may use the option of PPSX file conversion to a different format.
We hope we helped you solve the problem with the PPSX file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.
There can be more reasons which determine that you are not able to open the PPSX file (apart from the lack of the proper application installed).
First - the PPSX file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the PPSX file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the PPSX file should be solved.
Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the PPSX file has not been completed and it cannot be opened properly).
