Error unexpected file format! Help

hi yesterday I worked all day on a project and this morning I appeared the words “unexpected file format”
I tried the solutions written below but nothing. Could someone help me ? thanks


There was no problem to open for me…. I purged it:

With what sketchup verisone you work ?
I don’t understand why your version doesn’t open up to me, it’s frustrating.

Saved to previous version (2020)

thank you from the bottom of my heart!
It works !!!

Your forum profile shows you are using the current version, SketchUp 2023. Is that not correct?

That could be correct …It is very likely that she/he has an earlier version than I (or You) do. :closed_lock_with_key:
