Cortex runs it's own built-in FTP server for you to log into and work directly with your instances's files. Using an FTP client log into port 4365 on the IP of your game server with your Cortex username and password. Once logged in you should see a single folder called instances. Inside the instances folder is one folder for each instance you have installed on the server. The instance folders in the FTP server are tied in to what you see in the filebrowser. You'll only see instance folders for instances where the admin has assigned enabled filebrowser permissions for it. Likewise the instance folders and files on your FTP server have the same view and writing permissions as the filebrowser for that instance.

The FTP server does not run over a Cortex cluster. When logged into the FTP server you'll only see instances that are installed on that server. If you have a cluster of Cortex servers you must FTP into each server individually.

The default Windows command line FTP client has issues connecting to Cortex's FTP server, and we do not recommend using it.
