About WoW's WDB Cache Files

Welcome, Adventurer! Deep within your World of Warcraft Classic folder lies a treasure trove of data: the WDB cache files. These files (like `creaturecache.wdb`, `gameobjectcache.wdb`, etc.) are your client's personal diary of its journey through Azeroth. Every time you encounter a new creature, interact with a mailbox, or discover a new flight path, the game saves a little bit of information about that object into these binary files. This allows the game to load that information more quickly the next time you see it, reducing the need to constantly query the server. While these files are written in a complex binary format that you can't just open in a text editor, this tool acts as a powerful decoder. It allows you to safely parse these files right in your browser, translating them into a human-readable format so you can see exactly what your character has seen and done.

How to Use The Parser

Unlocking the secrets of your cache is simple:

1. Locate Your WDB Folder: In your WoW Classic installation directory, navigate to `_classic_era_` or `_classic_` -> `WTF` -> `Account` -> `[Your Account Name]` -> `[Your Server]` -> `[Your Character]` -> `Cache` -> `WDB` -> `enUS` (or your client's language). This is where you'll find the `.wdb` files.
2. Select Your File: Drag and drop any `.wdb` file from that folder onto the upload area, or click to browse for it on your computer.
3. See the Data Instantly: The moment you select a file, the tool will read and parse it right in your browser. A clean, searchable table will appear, showing you the contents of the file.

Because all processing is done on your own computer, your files are never uploaded, ensuring the process is both instant and completely private.

Tips for Azerothian Archaeologists

• What Can I See?:** `creaturecache.wdb` will show you a list of every unique creature your character has encountered, including their name and entry ID. `gameobjectcache.wdb` does the same for objects like mailboxes, chests, and herbs. It's a fun way to get a "history" of your character's interactions.
• For Addon Developers:** This tool can be incredibly useful for addon developers who need to understand the structure of the WDB cache or who need to quickly find the Entry ID for a specific creature or object without having to look it up on an external database.
• Client-Side Only:** This tool is a *viewer*, not an editor. Modifying your WDB files can cause your game to crash or behave unexpectedly and is generally not recommended. This tool provides a safe, read-only way to explore the data.
• A Word on Versions:** The WDB format has changed slightly over WoW's long history. This tool is designed to parse the format used in modern WoW Classic (Era and Wrath of the Lich King Classic), which uses the "WDB5" file signature.
