It is best not to tamper with any files in the Warcraft folder. For example, if you delete a decimal point, somewhere in the game, you say resurrection, and you will find, alas? Sister angel left, that's all. The game program of Warcraft is very complicated, and there are naturally many files. You can put the World of Warcraft folder on a separate disk. Many WOWER are doing this now, and they are all trying to adopt by hand.
