If you want to transfers files directly from one server to another

You cannot.

SFTP protocol does not allow this at all.

With SCP protocol it may be theoretically possible. However it has many drawbacks. It would require not only huge changes in WinSCP, but also many extensive configuration changes on both servers to allow authenticate on the second server from the first one (note that it would not be possible to use password authetication). So practically it would not have any advantage for most users.

Unfortunately WinSCP does not support this too well, but you may open two instances of WinSCP, connect to each of the servers and then use drag&drop between them. Note that you need to have disabled the drag&drop shell extension first. Files will be transfered thru your local computer, using the temporary folder of your workstation.
