Server file location of a Sub-domain fie on WP Multisite install

I want to access this file via FTP

http://vip.do*t**rp.com/wp-admin/css/login.min.css

Hosting cPanel by Godaddy

In my File Manage I see wp-admin and wp-content folders in the public_html folder. Which domain would that be for?

What would be the exact file location (directory structure) of the above file?
