Hi Jonathan Billings, the `age` can't apply to 'r', only would apply to 'd', 'D', 'x', 'X', etc "The age field only applies to lines starting with |d|, |D|, |v|, |q|, |Q|, |C|, |x| and |X|. If omitted or set to "|-|", no automatic clean-up is done." so, there have good idea if I only want to delete the specific files not all files in that dir? thx.
