Which model use to show path to files and show it in django

I have a django project and lots of media files on server, how to show path on server to file in django admin, to show file in page. I want it to don't upload 2 times to server.

Example: Movie with size 10GB in server

If I will use "FileFied", I will upload it to server again.

Can I show just a path and show in page
