Please post logs files from WinSCP and FileZilla for comparable operations.
I develop a C# application that connect to FTP server and download directory with many sub-dir and files.
When I use an explicit secure connection, I have an error message "MLSD can't retrieve directory listing"
When I deactivate the explicit connection and activate to connect with active connection, the application start to download the files and it stop after a few minutes.
When I use WinSCP application I have the same problem. But when I use FileZilla, all is ok also when I connect with explicit connection.
Do you have any idea
Thanks.
