The third tab is Folder Observer. Folder Observer allows you to define a local folder that will be watched. Each file and folder copied to the watched folder will be sent to the defined remote servers.
If Folder Observer is active, the Folder Observer will continue to work even after quitting Viper FTP. When any new file of folder is detected in the observed folders, it will be sent to the Transfer Manager and uploaded.
