The task FTP List Files will give you a remote file listing.
When you have the logging enabled on the connection, this task will also show you the FTP command / response logs in the file listing.
Now it's not possible to have a clear remote file list and use the same connection in a different task with logging on this connection turned on.
I like an option in the FTP List Files task to ignore the connection logging setting and show only the files.
