Where on the hard drive are macros stored?

I'm wiping my hard drive, but I would like to save all of my WoW settings. What do I need to save to make sure that I don't lose my macros?

Warcraft folder > WTF folder > Accounts folders - macro.cache(Account macros) > Character folders - macro.cache(character specific macros)

Save your account folders or just the macro.cache files themselves. If you want, you can just save the whole WTF folder as well, but that sometimes creates bugs.
