How to send files via the ServerSocket and ClientSocket in Delphi XE8?

Hi, I like to create, and this love programming, programming - this is my hobby.
You did a good Delphi program, I like it very much. At the moment I'm using Delphi XE8.

When I was working in Delphi 7, I had a program that can transfer the halyards on the client-server type.
And it worked, but when I moved to Delphi XE8, the code stopped working. Used ServerSocket component and ClientSocket.

I looked at the FAQ file transfer example:
http://docwiki.embarcadero.com/CodeExamples/Berlin/en/TTcpServer_(Delphi)
http://docwiki.embarcadero.com/CodeExamples/Berlin/en/TTcpClientSendStream_(Delphi)

but there used the old principle of the components of the TcpClient and TcpServer, who apparently removed from Delphi XE8.

Question: How to return the components TcpClient and TcpServer in Delphi XE8 or better how to send files via the ServerSocket and ClientSocket?
I not found anywhere normal documentation on this subject. Help me please.
