I just downloaded SmartFTP 2.0 and when I tried to send files to a Z/OS machine, the Z/OS machine rejects saying it does not support MDTM. I went into SmartFTP and disable keeping the time options from File options and it still kept sending MDTM. Is there a way to turn off MDTM? I had to go back to using an earlier SmartFTP (Ver 1.1.986.) client to get the files to work with Z/OS.
