FTP Script Task Using Connection On SSIS

Hi,
under the script that I use for upload file using SSIS asp.net task.


My problem....
If I comment this line
'ftp.SendFiles(files, "", True, False) ' the True makes it overwrite existing

upload made successfull without failure instead If I leave uncomment I got an error but files upload anyway correct.

Someone can give me some explains about this behavior?

Dim cm As ConnectionManager = Dts.Connections.Add("FTP")
'create the FTP object that sends the files and pass it the connection created above.

Try

Catch ex As Exception

ftp.Close()

Finally
ftp.Close()
