Which file on ftp contains user info?

Hey, which file on the webhost ftp contains user info, is it possible to add/delete users this way?

Coppermine stores all user information in your MySQL database, not in any file you have access to via FTP.  You can use phpmyadmin or a similar tool to add and remove members but it's better to do that inside Coppermine as an admin.
