WoW Client Folders: WTF, Interface, Cache, Data
Vanilla WoW Classic 1.12 · x5 realm · wowx5.ruUnderstanding the WoW 1.12.1 client structure saves time on any failure: you know exactly where settings, addons and cache live, what to delete for a reset and what to keep. Let's cover the key folders.
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.
