In looking at the various slide shows I've done over the years, I see there are many file extensions: Application files, movie clip files, ProShow Slideshow files, VOB, and PXC files. I'm in a quandary as to why all these extensions, can't recall having to make a choice. My latest slide show is a PXC file, and when I click on this show (it's listed in My Documents), I get asked "How do you want to open this file?". I click on "Look for an app in the Store" and the response is "Your search for PXC had no results". If I click on "More Apps", my choices are: Internet Explorer, iTunes, Notepad, Office XML Handler, Paint, Photoshop Elements 14 Editor. Then there's the option to click on "Always use this app to open .pxc files". I am using ProShow 8 and now have Windows 10. When clicking on any of the VOB, Application, Movie Clip & WMV file shows, this takes me right to the actual video to watch. But clicking on the ProShow Slideshow file extension shows just takes me to the ProShow Gold Interface, where you put together your shows. I know I can then watch the actual video, but seems there should be a quicker way to do that! So basically, two questions: PXC file extension and ProShow Slideshow file extension.
