#move(pathname, new_name) ⇒ Object

Both rename and move perform an FTP RNFR/RNTO (rename). Move differs because it first changes to the parent of the source pathname and uses a relative path for the RNFR. This seems to allow the (Microsoft) FTP server to rename a directory into another directory (e.g. /subdir/target -> /target )
