Ok, I sometimes use scp but more rarely now that I have a rsync command
in helm, also last time I tried, scp method was not supporting more than
three file at the time (marked files), see
https://github.com/emacs-helm/helm/issues/1945.  
For smb I never used it.

Thanks, will try as soon as possible.
