How to use rules.

[Rdgeno]

I'm trying to use the rule best64.rule. I'm typing in -m 2500 -r rules/best.64.rule capture.hccapx rockyou.txt and I keep getting in red rules/best64.rule: No such file or directory. I get the same when I try one rule to rule them all and whatever else I try. What am I doing wrong?
