[Discuss-gnuradio] gnuradio-companion : File Descriptor Source module usage

Can anyone explain how to use the File Descriptor Source module in
gnuradio-companion?

I am trying to write a flow-graph to read data from an arbitrary file,
chosen via the GUI at run time? This must be possible, right? I can't
see how to do it.

Thanks
Tom Crane
