stop prompts when saving in 2010 AutoCAD

[barry2104]

hi all

I work using AutoCAD 2010

i think an old drawing that i have taken over was created using cad2007, and due to the compatibility issues between them, every time I save the dwg (Ctrl+S) i get prompted/asked whether I realllly want to save the drawing in 2010 format (yes/no)

It's always yes.

 

is there a way to permanently disable this prompt either:

- for just this drawing, or

- for all dwg's i work on in the future

 

??
