VR Viewer - Windows - opening models that are NOT on the main computer C: Drive

HI all,

In the help section it says that for opening up files I can ‘browse your computer or hard drive.’

The issue is the only drive I can see is C: drive. The viewer will not let me change to other drives that are physically in the same computer (D,E) or for any network drives that are also mapped and connected.

Having to copy or save the file all the time to my desktop is doing my head in.
