WinSCP cannot download file when it's absent from directory listing.

I do not know why is empty, is not my server I just know that is a mainframe and the file is a dataset. This is the vbs scrip that I need to replace this vbs get the file.



' GENERATE FTP SCRIPT
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objMyFile = objFSO.CreateTextFile("E:\Scripts\atorres_test\ftp.txt")
objMyFile.WriteLine ("open scc.its")
objMyFile.WriteLine ("UserName")
objMyFile.WriteLine ("password")
objMyFile.WriteLine ("lcd E:\Scripts\atorres_test")
objMyFile.WriteLine ("get 'ATD.LAM.PODBS.P.LOT.F2R0050.V99' file.txt")
objMyFile.WriteLine ("close")
objMyFile.WriteLine ("bye")
objMyFile.Close
Set objMyFile = Nothing




' EXECUTE FTP
Set objShell = WScript.CreateObject( "WScript.Shell" )
objShell.Run ("ftp -s:E:\Scripts\atorres_test\ftp.txt")

Why is the directory listing empty? Is this how your server works?

I cannot get a dataset from mainframe using .net assembly if I use windows command prompt I I get the file.
Here is part of the code I use

using (Session session = new Session())
{
session.ExecutablePath = winscpPath + "WinSCP.exe";
session.SessionLogPath = LogFilePath;
SessionOptions Options = new SessionOptions
{
Protocol = Protocol.Ftp,
HostName = hostName,
UserName = userName,
Password = password,
PortNumber = port
};

session.Open(Options);
TransferOptions transferOptions = new TransferOptions();
TransferOperationResult transferResult;
transferResult = session.GetFiles(remotePath, tempLocation, false, transferOptions);
// Throw on any error
transferResult.Check();

// Print results
foreach (TransferEventArgs transfer in transferResult.Transfers)
{
// Console.WriteLine("Download of {0} succeeded", transfer.FileName);
message = "succeeded";
}


}


Here is the WinSCP log
