I'm using the current Lightroom on my PC.
Some months ago I made a couple of slideshows, and saved the projects. Now I forgotten where I stored them.
How do I locate them. Do the files have a particular suffix which I can use to make a search?
Would they show up in the Library? If so, how do I distinguish them from other images?
They have a Video format or PDF extension depending on what option you chose at the time.
The exported file(s) probably have an MP4 video extension.
In the Library, the slideshow should be listed with your Collections.
