That article is about WinSCP GUI.
If you want to automate moving files (transferring – to be exact) between two remote servers from a local machine, then you need to run an appropriate command (like scp/sftp/wget) on one of the servers. That's not really task for WinSCP. You can do it using the call command. But that's an overkill, if you do not use WinSCP for anything else. An ssh or plink are more appropriate tools for executing a command on a remote server.

I found it in docs https://winscp.net/eng/docs/faq_fxp#custom_command
that's why I posted it here.
Can you please tell me where I get any solution for this?
