The Dir() command returns an array with the filenames in my directory but with the DirDetails(".") nothing comes in return.

Please enable logging (see the Dev Guide) and post the log.

Also, log in with an ordinary FTP client and do a full listing of the directory with 'dir' and post it.

In the directory there are only three files.

This is weird behaviour, as you can see that 550 is returned on one LIST, then 3 files are returned on the subsequent LIST.

Can you post the listing returned by typing 'dir' in the FTP command line?

There is now 5 files in the directory:


ftp> cd ftptest
250 "D610.FTPTEST." is the working directory name prefix.
ftp> dir
200 Port request OK.
125 List started OK

Ah this explains a lot. We've not seen this format before and our parsers won't be able to parse it. So DirDetails won't work until a new ZOS parser is written.

So the DirDetails won't be able to parse the textfile (SPORT.TXT) either?

I don't understand. Can you please explain what you mean?

DirDetails basically gets a stream of text that is the same as that returned by 'dir' in a commandline client. As the ZOS format is unknown to DirDetails, it fails to parse the data to convert it to FTPFile objects.

SPORT.TXT is never parsed by FTP clients, it is just a file on the FTP server.

A new parser must be written to cope with ZOS directory listings. You can write it yourself or EDT can write one for you (although we will charge for our time in doing so - probably 3 hours of time including testing). Contact us at support at enterprisedt dot com if you want us to write one.

So the DirDetails won't be able to parse the textfile (SPORT.TXT) either?
