We added support for MDTM-modify in CuteFTP Pro v3 due to popular demand. We
simply issue a FEAT command and if MDTM is supported and if the user has
opted to retain the current timestamp of an uploaded file, we simply attempt
the MDTM-modify sequence. If it fails we notify the user via the log. More
and more servers are adding support for both MDTM-query and MDTM-modify. It
would be nice if MDTM-modify could be formalized in an upcoming RFC or
draft, as the market wants it and it is very helpful for folder
synchronization, overwrite comparison and other such tasks.
