Unexpected File Format on my file

Hey! I really need help.
I tried opening a file and the “Unexpected File Formart” error appears, I tried to change the file name and format, but i can´t open it…
It’s my final project of college and i really need to open it :frowning_face:
If someone could help me i will be very glad
Thanks

If you share the .skp file @colin might be able to work his magic on it and at least recover components and materials.

Where were you saving the file? On your local drive or to the cloud?
