How to save sketchup 2025 in 2020 version?

Hi, I bought sketch up 2025 but my sketchup 2020 doesn’t open projects in 2025. Do you know how solve this problem?

hello

Yess, it works! Thank you:)

You can also use Su4U’s SaveAs programme. As this is a standalone program, anyone who only has an older version of sketchup (2017 or 2020) can use it to convert a recent sketchup file and then open it.
