For completeness:
-
I received help on the Embarcadero forum which is back on-line, and
the following command does what I need:

FTP.List('CVS*.zip', false);

The first argument is a file name specifier string including wildcard
* and the second is a flag to supply full information (true) or only
the file names (false).
With this in place my utility works and the code is now much cleaner.

In fact the windows7 command line ftp client can do this:

ftp> ls CVS*.zip
200 PORT command successful.
150 Opening ASCII mode data connection for file list.
CVS_Config_2017-09-28.zip
226 Transfer complete.

Is there a corresponding way for IdFTP to perform a wildcard list and
returning just the matching files?

Thanks!
That did the trick!
I was looking down the Windows Firewall settings to see if something
there blocked the communications...

It turned out that the old code *had* an FTP.Passive := true;
statement hidden away where I did not notice..

And my code for retrieving the list was also incorrect, I needed
FTP.Listresult for that.

Question:
-
The result off of this Windows server looks very much like a Linux ls
-l command result:

-rwxrwxrwx   1 ownergroup1572 Sep 28 15:30
Config_2017-09-28.zip
drwxrwxrwx   1 ownergroup   0 Nov 13 19:30 AGIENG
drwxrwxrwx   1 ownergroup   0 Nov 22  1:05 CVSREPOS
drwxrwxrwx   1 ownergroup   0 Nov 11 15:44 FULLREPO

Is this how it always looks like or is there a way to format the list
into something less Linux-ish?

I need to get a list of the files that match a specific format like:
_.zip
I could of course traverse the supplied TStrings and look at the first
char (discard all d entries) and check if the last part is .zip.
But it would be a lot easier if the list could be limited to the
filenames only.

The FTP.List() command has a number of overloaded versions and I have
yet to find a working documentation of these. So in the absence of
Remy Lebeau I am hard pressed to figure it out. And tracing down the
Indy sources is not an easy task.
Maybe one of them will produce a simple file list only?

Set FTP.Passive := True.  PORT is used for active connections, where the 
server opens a connection to the client computer for the data stream. 
PASV is used for passive connections, where the client opens a second 
connection to the server.
