If Network Trace is enabled, File Contents Viewer cannot be.

The network trace is for use when you need to trouble shoot a connection. It starts to display the control port traffic for all active connections when you enable it. This gives you an on-line display of control information rather than a record of it in a file, which you can obtain using the Capture to file option on the File menu or on the Connect to Host dialog box. The network trace includes control information for all active connections, whereas a capture option limits the scope to one connection.

Control port information comprises the FTP commands you send to other systems and their responses. It does not include any file content. The following is an example of control port traffic.
