But it might be something else entirely....
Just about anything WSFTP and FileZilla can do, TIdFTP can do too (with some work). You are going to have to study the underlying FTP commands that WSFTP and FileZilla exchange with the server, and compare them to the commands that TIdFTP exchanges, and then tailor TIdFTP to mimic the same commands.
Most notably, have a look at the TIdFTP.ClientInfo property. By default, it is empty, so TIdFTP identifies itself as Indy to any FTP server that supports the CLNT command. You can change the ClientInfo values to make TIdFTP identify itself as other FTP clients if needed. That might be enough to get the behavior you are looking for.
