Thanks Dan and Uma, glad I seem to have hit on an issue. I use
Windows XP prof. When I right click on the wav file I can indeed see
the metadata property fields I'd love to fill in but it won't let me
access them. Is there some way to unlock this and fill them in ?
That's all I really want.

header information without even opening the wave files - a huge time
saving when you are working with multigigabyte files. but of course
with windows vista (and probably the newer versions of mac os) you
can get at this information, including the ability to organise and
edit the information in windows explorer, so you may not need
addtional software. just right click on the file name and go to
properties.
