WinSCP - using the SFTP protocol, which the ssh server on the Pi provides - would be a better file transferring tool than the outdated/insecure "scp" command.
The command 'scp' != the protocol 'scp'.
The scp command does not use the scp protocol anymore since openssh 9.0 but uses the SFTP protocol by default.
