Copying files from one server to another through a .NET Windows application on my local machine

Question

I have a Windows application built in C#, .NET 3.5. One of its functionalities is to copy files from ServerA to ServerB. The application will be run on a client machine, ClientX.

What is the most efficient command/way to do this in C# so that the files are not temporarily buffered in the ClientX machine by the application?

So the flow of the files should look like:

ServerA ----> ServerB

and NOT like:

ServerA ----> ClientX (temporarily buffered internally by .NET) ----> ServerB

Answer 1

One possibility would be to use the File eXchange Protocol which uses FTP to do a direct transfer from one server to another without the file ever visiting the client.
