I'm thinking about reformatting my hard drive and reinstalling all software including WoW and I was wondering which files to copy so that I don't lose all of my formatting and configurations for all my addons and screen layouts and what not. I know that the WTF file is one of them, but is there anything else? I box 5 accounts from 1 WoW install (application folder) so I would hate to have to reconfigure everything again. Thanks.
