I seems you still have not fully understand the fundaments of gstreamer:

copy *any* file:

gst-launch filesrc location=sample.wav ! filesink location=test.wav

copy the file only if it is a wav (decode and reencode):

gst-launch filesrc location=sample.wav ! wavparse ! audioconvert ! wavenc ! 
filesink location=test.wav

In you first example you forgot the encoder, thus it would only write out raw data.
