Data (not dota. . . The folder inside contains ZHCN, zhcn, cache and interface, and other folders can be deleted.

The following is what I saw on nga. You can refer to it.

First of all, please look at the file name to be deleted below, and don't remember it wrong!

Prerequisite: Make sure that the client file has been updated, otherwise an error may occur!

World of Warcraft client slimming first step:

Delete all other folders in the World of Warcraft directory except the World of Warcraft/Date folder. Note: The folder mentioned above is not a file.

World of Warcraft/Interface-This is the plug-in directory. You can cut to another folder for backup.

World of Warcraft/Interface. Obsolete

World of Warcraft/Log Error

World of Warcraft /CacheNew

World of Warcraft/Cache

World of Warcraft /WTF- This is the settings folder. You can cut to another folder for backup.

World of Warcraft/Update

World of Warcraft /system32 file

World of Warcraft/Log

World of Warcraft client slimming step 2:

Delete the following folders: World of Warcraft/Date/Cache.

World of Warcraft client slimming step 3:

Delete locked files and unofficial patches ending in ".". "Lock" is in the following three folders (that is, the MPQ file that you put into the client and does not belong to the client itself, please check it carefully before deleting it).

World of Warcraft/date

World of Warcraft/date /enCN

World of Warcraft/date /zhCN

Note: Do not delete the entire folder!

Ok, now your World of Warcraft client is simpler. Next, don't log in to the game. Double-click World of Warcraft /Launcher.exe to run normally. If you need to download some data, wait until he finishes downloading, and then log in to the game normally.

Problems that are easy to occur after the World of Warcraft client is slimmed down:

However, after deleting the data/cache, it may:

Some people may not be able to update, some people are stuck, some people are told that the client is damaged, some people receive new small blue bars when they go online, and there are scenes with incomplete pictures.

Solution:

Solutions to various problems:

1. Back up the client first to prevent you from deleting some files by mistake.

2. Delete the cache folder in the WoW directory.

3. Delete the cache folder of data in the WoW directory.

4. Run Launcher.exe and wait patiently.

5. At this point, you will be prompted that it is being applied. New data/cache is actually being generated.

6. The application is completed! Press to start the game.

As long as you run the game, a new data/cache will be generated, and there is no upper limit on the total size!

To sum up:

The folder Data\Cache can be deleted (sometimes some wrong caches will be generated, leading to various problems. This folder will grow secretly with the progress of the game, which means that both Launcher and WoW can be generated. Maybe it will save its state in a configuration file (cached in the wow directory), so that the initiator will not be regenerated automatically after deletion. Delete some configuration files (cached in the wow directory), which Launcher can apply to the cache)

Some errors occur because WoW thinks it has some data/cached data, but it doesn't.
