Me too! if anyone has any other ideas that would be appreciated
Open Sketchup, make a new file and save it with a name you can search for. Then find that file to determine where Sketchup was/is saving your files. Or maybe choose save as and see what the preloaded pathway is? Not sure if windows works that way. Anyway somehow you need to make sure you are saving your files in the proper place on your pc in the future. If you can determine for sure that the files were being saved to a temp folder at least you will know what happened.
It was saving so a temp folder, but yeah will know for next time, but the file i was looking for is not there.
