The Site page is where you specify the basic configuration for a site entry in the FTP Address Book.

Please note that the secure FTP options require the purchase of the optional Advanced FTP feature.      

The first entry in the drop-down list is Automatic (Serv-U). This is a special option for when the remote FTP site is running the Serv-U software, which has special provisions for timezone handling.

For security in a corporate environment, it's possible to prevent Opus from saving FTP passwords, using an administrator-only registry setting. To do this, set the PreventSaveFTPCredentials value under HKEY_LOCAL_MACHINE\Software\GPSoftware\Directory Opus to DWORD:1.
