Maxsurf - Save As Design Error

Hello everyone,

I hope all of you is fine Slight smile

I want to ask a short question. After setting the model in modeler, I save it on the desktop. When trying to save the file in another folder, I get the following warning.

How can I save the model in another file, I don't want it to stay on the desktop all the time. Also, copy and paste does not work.

Best Regard.
