I wonder if anyone can help me, I have been working on a rhino file for a fair few hours, I saved the file and closed the application. When I tried to re-open my rhino file came up with this pop- up shown below saying this is not a rhino file. I have then gone on to open it on my laptop but this has not opened either. Could anyone possibly help me or advise me on how to retrieve my work within this folder.
Many thanks in advance.
