It will not harm your system in any way, it will only deletes your cache folder and then runs wow automatically. Why do this? Well, we update the database several times a day with the latest fixes. The cache holds a general copy of everything you see in the game. So, if you get a quest when it is broken, and later we fix it, you won't see the fix until you delete your cache. This is *very* important, clearing the cache will ensure that your game experience is as good as possible and that you run into the minimum amount of bugs. Note that this cache only holds temporary game data, it does not hold your preferences or your macros, so there is *zero* harm in deleting this folder.
