Search Message Rules in Win Live Mail

I have tons of message rules set up and scrolling through them to check for duplicates is time consuming.

I’m wondering if there’s a way to search message rules I’ve setup so I don’t have duplicates - I’m thinking I would need to get into the file where they’re stored.

Or should I just not worry about it?

Do message rules appreciably affect performance or is it the kind of thing where Windows can check hundreds of rules in less than a second anyway so who cares?
