WOW Expansion HD Space : World of Warcraft General Discussions

Drysc gives a little knowledge to those wondering about how much space total for the game + xpack, have a listen...

After upgrading one of the machines here on a fresh install, nothing additional aside from the 2.0.0-2.0.3 patch inside the directory, the total size of the World of Warcraft folder with the expansion installed is 6.6GB. I'm guessing that's a pretty decent guideline. Keep in mind though that while patching additional space will be needed to create temporary files, so it's always good (and necessary) to have more room than just what the game requires.

Thanks
