WOW updated files can't be deleted, which will lead to file damage and the game can't be played. You can reduce the memory usage by downloading the client again, as follows:

Need tools: computer, World of Warcraft

First, find the installation directory of World of Warcraft, and cut the screenshot folder under _retail_, which contains screenshots of you in the game.

Second, then delete all the installation folders of World of Warcraft.

3. Log in to World of Warcraft official website and click "Game Download";

Fourth, choose Battle.net client download or green download.

5. The client of World of Warcraft only needs nearly 60G, and the old installation package after several updates is 100G, which can be slimmed down by this method.

Six, after the download is completed, you can enter the game.
