In a word no, they are copyrighted.
Recipes cannot be copyrighted
http://www.copyright.gov/fls/fl122.htmlWhile BCS can and should fall under the realm of a cookbook, thus can be copyrighted, the recipe itself is not.
Correct me if I'm wrong here - I realize Beersmith may have had legal advice regarding this matter and I'm just interpreting the issue incorrectly.
This particular issue annoys me, frankly, because I purchased the book, I have the recipes, I just want them in a convenient format. If there was a means to purchase said file, I would have no problem with that. But, there isn't a commercial alternative so the next option is asking the share files with fellow homebrewers.
