I am having trouble opening Pro-E files in Solid Works.

I went to File > Open > and changed the file file to Pro-E/Creo    ---   But the part will not open when I attempt this.

Is there another way, or is it just not possible?

I have never used (or had access to) Pro-E. Can Pro-E files be saved as Solid Works files to make it easier to send receive from customers?
