In other words, what do I...or can I.. use as the default association for *.bwf? *.wav will either open Windows Sound Recorder or one of the free sound-file players I have installed...and I will hear the contents of the sound file. *.mp3 does likewise...which is why I can click on "Hear the song" on many web sites and hear it. If *.bwf has no equivalent, readily-available default player, then it would be great for archiving sound files (if you have the program needed for playback)... but not so good for making an archive accessible (which, IMO, it should be!)...
