I will start off by saying that I don't have a Priv so I can't test this.
Since the Priv is Android (and not OS 10) does Link even play nicely with it?
Last time I remember Link, it barely worked with OS 10 devices.
This is how I do what you want to do with the Galaxy S7 Edge:
To get the Android drives to appear to the PC, connect the Priv to the PC, then go to the Home Page. Swipe down from the Top of the screen, and click on where is says that USB Charging is underway. You should get an option to change to File Transfer. Once you select that, the Android file system will appear on you PC.
At least I hope so
Good luck!
