COMODO Firewall 2013 (v6) allow internet access whole folder branch

It seems option to allow folders (as in c:\some_folder*) in firewall rules is no longer possible in latest version. Is there a walk-around for this limitation?

There is a workaround for this. You will have to add the folder you want to add as a file group. Go to Defense + → File Protection → Groups to add the group.

Thank you very much, It does exactly what I need. I would not found this without your help.
