Issue with custom receive Pipeline component

Question

I have been facing issue with creating a custom receive pipeline component. The Pipeline is to receive large file, if the file size is large it has to read the incoming stream to a folder and pass only some meta data through the MessageBox. The Execute method
I am using is,
#region IComponent Members
public IBaseMessage Execute(IPipelineContext pContext, IBaseMessage pInMsg)
if (_largeFileLocation == null || _largeFileLocation.Length == 0)
_largeFileLocation = Path.GetTempPath();
if (_thresholdSize == null || _thresholdSize == 0)
_thresholdSize = 4096;
if (pInMsg.BodyPart.GetOriginalDataStream().Length > _thresholdSize)
Stream originalStream = pInMsg.BodyPart.GetOriginalDataStream();
string largeFilePath = _largeFileLocation + "\\" + pInMsg.MessageID.ToString() + ".zip";
FileStream fs = new FileStream(largeFilePath, FileMode.Create);
// Write message to disk
byte[] buffer = new byte[1];
int bytesRead = originalStream.Read(buffer, 0, buffer.Length);
while (bytesRead != 0)
fs.Flush();
fs.Write(buffer, 0, buffer.Length);
bytesRead = originalStream.Read(buffer, 0, buffer.Length);
fs.Flush();
fs.Close();
// Create a small xml file
string xmlInfo = "<ns0:MsgInfo xmlns:ns0='http://SampleTestPL.SchemaLocation'><LargeFilePath>" + largeFilePath + "</LargeFilePath></ns0:MsgInfo>";
byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(xmlInfo);
MemoryStream ms = new MemoryStream(byteArray);
pInMsg.BodyPart.Data = ms;
return pInMsg;
#endregion
Here I want the xml to be dropped in to the File share Eg: E:\Dropbox\PL\send and and the entire message to be dropped in the folder Eg: E:\Dropbox\sendLarge. so in the ReceivePipeline properties i set like
And in the send port the destination i give is E:\Dropbox\PL\send.
The issue is both the xml and the message are getting dropped in to the same folder E:\Dropbox\PL\send and the message is not getting dropped in E:\Dropbox\SendLarge. Any help is greatly appreciated.
