On the left menu, choose “Your system” / “Auto-mount center”
Click on the “Create a connection” button
Select FTP directory on the protocol wizard.
Under credentials informations wizard, set the address of your FTP server in Remote server name field, the account and password to access to the FTP service and the remote FTP folder shared for this account in “Local Directory name” ( if you did not have a FTP remote directory to define, type “/” )
You will see the local directory that points to the remote FTP service.
Just after adding the connection, the folder icon will be "red", which means that it is not ready because you need to reconfigure the service.
Click on the “Reconfigure service” button
If you see a green icon, then your directory mount point is available and connected
