You can slim down the World of Warcraft folder by deleting the previous patch. In the update folder, as long as you have the latest World of Warcraft, delete everything in it.

World of Warcraft won't always be like this. Official website announced that World of Warcraft 5.0 will delete useless files in the later update. It is estimated that the whole World of Warcraft file is about 20G, so don't worry, it will be deleted when it is updated.

I'm sure wower who logged into World of Warcraft these two days found that the game was going to be suddenly updated during the login process. If this happens, don't worry or panic. This is just an advance update of World of Warcraft version 8. 1. But the size of patch pocket this time is somewhat surprising.

Only 16G is needed to update a version, and this does not include the Dasaro War started by the new regiment and some battlefields on the front line of the new war, only some gadgets are added in the 8.0 expansion.
