I'm finding some more the more I look. Things like (10\.10\.34\.34|peyvandha\.ir) being in the pattern set at the top means that the section of pattern later (10\.10\.34\.34|peyvandha\.ir| in the 120 day set is useless. Similar things in the "All files" set. * rar for example is listed twice, * (jp(e?g|e|2)|jpg matches jpg ... or jpg. Also when matching one character from multiple use square bracket syntax.
