title: GRC file meta sink how
body: <p>I'm new to GRC.  I want to modify the attached config to replace the "file sink" at the bottom of the image with "file meta sink", so I can use a program to read the header and then the complex samples. I guess I might need a different stream adapter, but it is not clear which one or how.</p>
  
  <p>Help please.</p>
  
  <p>Thanks,
  Don</p>
