Poul Bak's comment is correct.

As we know, .net core 3.1 webapp just support broswer to access the resource from the webserver. It can't do anything in client side.

If we want to do something on the client side, we can only call it through Javascript under the premise of browser security.

And it's not possible to get broswer download path with javascript.
