Main client folders

Folder	What it holds	Safe to delete?
WTF	Account settings, keybinds, Config.wtf	Carefully (you lose settings)
Interface	Addons (AddOns) and custom UI	Yes, addons reinstall
Cache	Temporary game cache	Yes, safe for a reset
Data	Game assets (MPQ archives)	No, the game won't start
Screenshots	Your screenshots (F12)	Yes, just images
Errors	Lua error logs	Yes, safe
Logs	Technical logs	Yes, safe

WTF — the heart of settings

The WTF folder holds Config.wtf (global settings) and the Account\<NAME> subfolder with keybinds, macros and bar layout. This is what you rename to reset a 'broken' interface. Don't delete it blindly — you lose all settings and binds.

Cache — the first thing to clear on glitches

The Cache folder can be deleted entirely: it is temporary data the game rebuilds. Clearing Cache is the standard first step for crashes, loading-screen hangs and odd glitches (see Crash on Loading Screen).

Interface — where addons live

Addons install into Interface\AddOns — each folder is one addon. If the UI broke after installing an addon, delete its folder here and reload the interface (/reload). On addon conflicts, see Addon Conflicts.

Data — do not touch

Data holds MPQ archives with models, textures and maps. Deleting or corrupting any file here guarantees a launch failure. If you suspect broken archives, it is easier to re-download the client.

FAQ

What does the WTF folder do in WoW Classic?

WTF stores global settings (Config.wtf) and an Account subfolder with keybinds, macros and interface bar layout. You rename it to reset a broken UI, but deleting it loses all your settings.

Which WoW client folders are safe to delete?

Cache, Screenshots, Errors and Logs are safe — the game rebuilds them. Interface can also be deleted (addons reinstall). But never touch Data — without it the game won't start.

Why is clearing the Cache folder advised for glitches?

Cache is a temporary store that accumulates corrupted data over time. Deleting it fully is safe and often fixes crashes, loading hangs and graphical glitches: the game rebuilds the cache.
