Those documents can be opened directly from any installed cloud provider like Google Drive, Dropbox or OneDrive. You can even send the documents via email or copy them to your device via USB and then open them with Royal TSD Free.
Connecting to the remote machines with RDP, VNC, SSH or Telnet is possible with specialized 3rd party apps.
With Royal Server you don't need to connect to the remote desktop anymore. You will see the Windows Events, Windows Services, Windows Processes, Terminal Services and Hyper-V and VMware virtual machines directly in Royal TSD Free.
With the full version you can also manipulate them or run PowerShell scripts on the remote machine.
E.g. if you find an error in the Event Log, then you could restart a service, kill a process, reset a Terminal Services connection or stop and start a Hyper-V virtual machine. When you use PowerShell scripts, then there is no limit of what you can do.
Some supported connection types can be tweaked and optimized for your mobile device. Remote desktop connections, for example, can be configured to always use a lower color depth or screen resolution to save bandwidth.
