Can you change a Sketchup File to Sketchup For Schools and back again

Is it possible to turn a Sketchup file into a Sketchup for Schools and then back again?

There’s no difference. Both programs use .skp files.

Thank You I asked this because the last time i tried this it told me it wouldn’t work

Was it a file you downloaded from SketchUp for Web and tried opening in an older version of SketchUp? If that’s the case, when you download the file to your computer, you should get a prompt to choose the correct version.
