Confirming this is how its done.....
To Open in MS Project (this what I have put together)
- Drag the file to your Desktop (very import to “drag” and not use any other method like copy/paste)
- Open the Microsoft Project application directly without opening any files
- Select 'New from Existing Project'
- You will get a pop up window to select a file, make sure to switch from a 'Projects' file to 'XML Format’ file
- Select the appropriate file name
- Click Open
- An Import Wizard window will pop up, please select 'As a New Project'
- The file should populate in standard MS Project format.
- You can now save as a MS Project File
