If you need to share same Site Manager information between all 3D-FTP installations in the network, you can make an entry to the registry in all workstations that are running 3D-FTP. You can find this registry entry is at
This registry setting specifies the location of the shared Site Manager file and sets 3D-FTP to share Site Manager mode. By default, all instances of 3D-FTP that use the shared Site Manager file open it as read-only. So no changes can be made via Site Manager. You can override this with the /M (=Master) command line switch, so start 3D-FTP with this command line:
3dftp.exe /M
In Master mode, the file is opened as writable and changes made to it are saved (and made visible to all 3D-FTP instances that use the shared file). This is convenient for admin PCs that can update the Site Manager information, while other installations can see the changes after 3D-FTP restarts.
If this "SiteFile" entry is not found in the registry, the SITES.INI file in the 3D-FTP installation folder is used for Site Manager information.
