Using 8.5.4.
I have to set up a job to download files from a partner's MVS or z/OS FTP server. As you know, that flavor of server handles "directories" differently from other servers. I have set up an FTP task with a Download command with the following (obfuscated) parameters:

• Folder: 'PREFIX.TREATED.LIKE.DIRECTORY'
  Include file mask: FILENAME.*

I am unable to download a file that I know is there (verified with a FileZilla session). It appears to me that the problem is that the prefix (with quotes) is being pre-pended to the file name in the RETR command. I suspect that if it were possible to make the RETR command use the file name only, it would work. Here is the logged output of the session:

220-FTPD1 IBM FTP CS V2R3 at external.ftp.server.tld, 11:40:13 on 2019-09-10.

I've tried tweaking a couple of different settings in the download setup, but nothing has made it work. Am I missing something?
