What had you specified as the destination?
Run this and check the stack trace to see which file was not found.

Actually we need to send the file to remote pc by specifing their path in destination textbox.if we use socket then we should open the socket from client side also and we install client program on all the client machine we not need copy the file in all client machine,so we need different solution other then sockets to accept datai.e dynamically the destination pc accept the data
