Thank you SMagic, but this is not the idea of my suggestion.
I try your method, and it need to know all my library to decide if a book is "SFK" or not, and if it is, it need to send the book in the good folder. its a work of one man on library of thousands books. (i also try to create kid folder with symbolics link, but its not working for me)
With a flag, every adults (ie every parents) can see ALL the books (no need to ask to himself if we want to read an adult book or a kid book) , and can decide if it's SFK or not and give access or not for the all the kids.
