Ignition 8.0.14 - windows symbolic link for Ignition webserver?

Ignition 8.0.14 - Windows Server 2016.

I use Ignition webserver for a tiles server.

All is fine but I would like to use windows symbolic link in order to store tiles in another directory outside Ignition webserver’s directory.

I’ve created the junction with:

mklink /J "C:\Program Files\Inductive Automation\Ignition\webserver\webapps\main\tiles" "D:\tiles"

In

C:\Program Files\Inductive Automation\Ignition\webserver\webdefault.xml

and

C:\Program Files\Inductive Automation\Ignition\webserver\webapps\main\WEB-INF\web.xml

I set aliases parameter to true

    <init-param>
      <param-name>aliases</param-name>
      <param-value>true</param-value>
    </init-param>

I restart Ignition gateway, but my files are not accessible with Ignition webserver.

Any Idea ???
