    google: Mark files you can't see on the web as hidden
    
    Files without the parent are currently shown in google backend root.
    You can see many files consequently, which are not shown in your google
    drive folder on the web. Those files can be shared with you, or you
    opened them in some google applications (i.e. google docs). Mark those
    files as hidden to see same files as you can see on the web. Also mark
    the files as undeletable, because it is not possible to delete them
    from the obvious reason.
