How can I ship a world on a minecraft nitrado server?

Please I need help have a Windows 7 system if necessary!

There's a Filebrowser, with which simply upload the world. Which files you need and where they are / should, you should find on Google.

That should be possible with the FTP protocol.

The FTP data should be found in the Nitrado interface.

You'll need to install an FTP client, like

WinSCP or FileZilla
