The application's interface allows you to have as many different servers open in different tabs as you need. You can also link a folder on your device to a folder in the server so it updates automatically whenever you modify something in it.
FTPRush is a comprehensive FTP client that can satisfy both the inexperienced users (thanks to how easy to use it is), and the most advanced ones (thanks to the many customization options it offers).
