Transferring FilesWS_FTP Pro Note When you turn on this option and click Set as Default, the option is set as the default for all sites; that is, it becomes the setting for all site configurations unless it is overridden by the settings for particular sites and folders.Doing Passive TransfersNormally, when you connect to an FTP site, the site establishes the data connection to your PC (the client). However, some sites allow passive transfers where your PC establishes the data connection.By default, passive mode is turned on in WS_FTP Pro; we recommend that you use it for most transfers from FTP sites that support passive transfers. Note, however, that passive mode may be required in the following instances: Local networks behind some types of router-based firewalls Networks behind a gateway requiring passive transfers Erratic transfers Repeated failed data channel errorsIn both the Classic and Explorer interfaces, you can turn passive mode on or off for an individual site. In addition, in the Classic interface, you can also use the program options to make the passive mode setting the default for all sites. Note The setting in the program options is overridden by the setting for the individual site (if they differ).Normal data connectionPassive data connection
