Media Browser should be able to view and link to UNC paths on Windows
Often organizations have more projects than available drive letters on particular Windows workstations.
It's best practice not to have to map network shares to particular drive letters, but instead to rely just on the UNC path: https://superuser.com/a/393435
However, the Media Browser within Premiere Pro, After Effects, Media Encoder, etc. is not capable of accessing data via UNC paths.
Please allow us to access UNC paths in the Media Browser so that we're not dependent on limited Windows drive letters.
