Do not show status message
Hide the detailed status information in the Trace window.

Send keepalive command to prevent disconnection
FTP Now will send dummy commands (NOOP) to the FTP server, so it will not timeout on you.

Interval (in second)
The interval in which dummy commands are sent to the server (default: 30 seconds).

Remove failed transfers from queue
When this option is checked, failed transfers will be deleted from the queue (in the transfer manager). If you do not check this option, all failed transfer will remain in the queue with the failed status information, so you can resubmit them again.

Enable simultaneous file transfers
With this option unchecked FTP Now transfers selected files for upload and downloads in one thread, files will then be uploaded/downloaded one by one. When this option is checked, all selected files will be uploaded/downloaded simultaneously (in a seperate thread). This can speed up the file transfers, but it requires high-speed Internet connection.
You can also enable parallel file transfer 'on the fly' by holding down the SHIFT key while pressing upload or download.
