Audible alert on completion
FTPSync will beep on completion of the compare process if this option is set.
Ignore seconds when comparing timestamps
Most FTP servers only timestamp files to the nearest minute. In most cases you would want this option set.
Ignore times of files older than ... days
Most FTP servers don't maintain the time of files older than 180 days. By setting this option the times of files older than the specified number of days will be ignored when running the comparison. Set to 0 days to disable this option.
