It depends on what you call access problems. The definition of the PRV
and OWN access codes is subscribers (resp owners) of the list by the same
name as the filelist. You can define your own access codes pointing to a
list by another name, of course, but you cannot call them PRV or OWN.
Also, nested filelists are not really sub-directories, as you can have
only one filelist with a given name.
