I think the simplest thing is to remove fileSupported for now.  Also if we limit the get/set of transferToDirectNotSupported to transferToDirect, and limit the get/set of transfeFromDirectNotSupported to transferFromDirect then it removes any confusion as to when the direct cases are disabled. I've done that now and updated the PR
