The only way I have found so far to check if a directory exists on a FTP, when using this code, is to check if cDirectoryContentFromFTP is empty.

                        ' FTP setup
                        loFtpWebRequest = System.Net.FtpWebRequest.Create(New Uri(lcURI))
                        loFtpWebRequest.Credentials = New System.Net.NetworkCredential(cUsername, cPassword)
                        loFtpWebRequest.Method = System.Net.WebRequestMethods.Ftp.ListDirectoryDetails

                        ' If we use FTP/SSL  (AUTH SSL)
                        If nNoFTPProtocol = 2 Then
                            loFtpWebRequest.EnableSsl = True
                        End If

                        loFtpWebResponse = loFtpWebRequest.GetResponse()

                        loStreamReader = New StreamReader(loFtpWebResponse.GetResponseStream())

                        ' Load the files into the string builder
                        loStringBuilder.LoadString(loStreamReader.ReadToEnd())

                        ' Initialization
                        cDirectoryContentFromFTP = loStringBuilder.oStringBuilder.ToString

As, if the directory exists, there will be at least an entry for the current directory, or two entries, assuming the current directory is under another directory. Is there any other way to do this better?
