Empty directory listing

Hello,
I'm encountering a strange behaviour when FTPing to one of my system. I have a directory there, containing 3 text files. I successfully connect to the system via WinSCP GUI, but I do not see anything in the remote directory, like the remote directory is empty. I have written the following script to get all the files from the directory without the need to use the GUI – the script looks like this:

    "open ftp://username:password@IPaddress/ -rawsettings ProxyPort=0" ^
    "cd /brmsftp" ^
    "lcd ""I:\BRMS Rcy rpt\""" ^
    "mget -transfer=ascii *.*" ^
    "exit"
And the script retrieves nothing. This is in the WinSCP log file (I have removed some confidential information):

WinSCP and FileZilla have the exact same issue where I have an empty directory listing when using their GUI.
But when I FTP to the system with PowerShell, I can use the ls command, I can see the files, and can use mget to fetch all of them.

Could you please give me some advice where to look for errors? What does it mean 'Cannot parse line'?

Many thanks for advices.

Re: Empty directory listing

WinSCP (and obviously neither FileZilla) does not support the format of directory listing your server produces for LIST command. What kind of server is that? Can you attach a complete log?

By "FTP ... with PowerShell", I assume you actually mean plain old Windows command-line ftp client. It uses NLST command instead of LIST). The NLST produces just list of file names without any additional details. For trivial needs of Windows ftp, it's satisfactory, as ftp does not need to be able to tell files from folders, nor know file timestamps. But for GUI client (or scripting client that supports directory transfers and preserving of timestamps), it's far from enough.

It is an IBM i partition. OS based on DB2. I have dozens of these and this is the only one I can't fetch the files from. It is the only one I receive a 'Cannot parse line' from.
I'm not sure about uploading a complete log. I can try, but I need to take care about removing some sensitive information. Is there anything particular you'd want, or I should look for, please?

I actually mean Windows PowerShell, not CMD.

So wouldn't site listfmt 1 help?
See https://winscp.net/eng/docs/faq_mainframe#path_ftp
As strange is may seem, using command namefmt I would normally use from one IBMi to another is not recognized by the server when trying WinSCP script:
> 2022-07-12 11:08:02.543 Script: namefmt 1
< 2022-07-12 11:08:02.543 Script: Unknown command 'namefmt'.
. 2022-07-12 11:08:02.543 Script: Failed
. 2022-07-12 11:08:02.543 Script: Exit code: 1
. 2022-07-12 11:08:02.559 Disconnected from server
I do not understand how is it possible (or how to say it), that apparently the files are there and WinSCP sees them, but the script says there is a kind of parsing error:

I have played around the FTP target server attributes as you provided in the links, without success.

Yes, that's right.

Re: Empty directory listing

The FTP command is site listfmt 1, not listfmt 1. And to call a raw FTP command in WinSCP script, you need to use the WinSCP call command.
call site listfmt 1
In your batch file, that you be this syntax:
    "call site listfmt 1" ^
(after the line with the open command)
