The idea is: a product on sale is ALWAYS protected, no matter if it is public, private or restricted. That "flag" just determs, if it is listed in our catalog or not (public/private) or if you can link to it directly at all...
restricted files are not "linkable" from the outside, they NEVER appear.
But that has nothing to do with the file itself, it just relates to the listing in the catalog for the descripton page... hope I put it clearly?
