Or just mount the target directory with sshfs() and use your favourite graphical file manager.
That is a shame but thank you for posting this very useful info. While sshfs is probably not what OP was asking for and sftp/scp!=sshfs it is definitely usable in that fashion.I haven't tried on FreeBSD 11 yet but on FreeBSD 10 the FUSE SSH filesystem never worked the way I wanted. It always errored out when traversing a large directory tree on the remote server.
sftp://servername/path
to login as your current user. If you want to login with a different user, then use sftp://username@servername/path
fish://
instead of sftp://
in the above.
