How the new Edge will handle file:// URI ?

Thanks narutards 

For anyone else interested, we changed all our file:// link references to localfile:// and implemented a new protocol handler in the registry.   

For example: 

localfile://open?data=\\NASORL1\EngData\MAVIS\ProjectTickets\13092\Engineering-Data\Prototype\

Since this issue only applies to our intranet web application that we've developed internally, it was an easy thing to deploy (you might be able to do it via group policy if you're running AD or via an easy EXE to make those if not).

Also, since this is a registry edit, the protocol will be recognized on any browser.

That's our work-around for now.
