Why do you want to do that?

You installed the Arduino software somewhere (C:\Program Files (x86) in rob's case, since he is using Win7 on 64 bit hardware). In that location (wherever that is on your computer), there is already a libraries folder, containing a folder called Ethernet, containing the source code.
