1. You might want to contact bookshare about the unpack tool; I would
think it should make a directory. Meanwhile I guess you make the
directory before downloading the book if you can tell unpack where to
put it. It's been a while since I had bookshare so I don't totally
remember how that works.
2. Finder had no trouble with the smil files I have but they may be
different in some way from the ones you downloaded from bookshare;
somebody else may have better info on that.
