Link from Dash App to remote folder

I am trying to create a link from my Dash App page to a folder on a remote machine.
I am using html.A(“Link to folder”, href=‘file://server/folder/’, target=’_blank’)
but it does not work.
It also does not work for a local folder.
For an external url it does work (but that’s not what I need).
Please advise.

I’m having the same problem. Were you able to solve it?
