Saving in Sketchup

Hello. Am wondering why it is taking SOOOOOOO long to save a SketchUp file? Not sure if I have too many files or need to somehow better organize them in folders(?) or save them somewhere else? Or do I have a setting chosen that I’m unaware of…These files are not complicated drawings—a wall or two, a floor and a ceiling- nothing fancy.

Also, can I change SketchUp from saving so often? It is saving files I’m changing before I get a chance to re-name them!!!

Thank you.
