Requirements and hyperlink to a file

I just verified : access via file:// protocole in html tags or via javascript has been banned in modern browser for security reason.
So it is impossible to acces a remote file via file:// from a web page, although it is possible to do it if you enter the link in the brower address area.
I also tried a window.open to the remote file:// link : still blocked with message "Not allowed to load local resource".
So it will not be possible.
Request is cancelled.
