Extracting Game Files
1. Monster Hunter: World packs its files into bin files, and the game pulls data from this. Fortunately, they added a method to overwrite the base game files with custom files, via using the same folder structure as the chunk.bin files inside of a “nativePC” folder in the root directory. To extract these chunk files we are going to need one of two tools. They are separated by functionality, one blindly extracting every file in the chunk folder, and another one allowing you to pick and choose what to extract. The one that lets you pick and choose can also dump everything, so it is often recommended to use it.

This is a program made by JodoZT, which allows you to pick and choose files, but also can do whole chunk extraction and merge all chunks before extracting. This is the recommended choice: https://www.nexusmods.com/monsterhunterworld/mods/411

This is a program made by MHVuze, which dumps the entire chunk file: https://www.nexusmods.com/monsterhunterworld/mods/6
2. For both of these programs you will need to copy a file for it to function. Capcom has stopped distributing the required file post Iceborne update, so you will need to get "oo2core_8_win64.dll" from another game such as Warframe (F2P) or STAR WARS Jedi: Fallen Order.

3. Where the application file is located you need to COPY this file to it. For example:

4. For WorldChunkTool all you need to do is drag the chunk folder onto the program and it will begin extracting in a CMD window. The extracted files will be written to the same folder where your chunk is located. Be aware of the estimated disk space required for extraction. Because of intricate technicalities, this estimate can vary by a couple hundred MB to a couple GB. Safe to say, make sure there is more than enough space on your drive before extracting the chunk.

5. The application will continuously inform you which file it is currently extracting, so you will know it's still working. It will take a while, just be patient.

6. A new folder will appear with the extracted files.

7. To use Jodo’s tool you just double click the application file (MHWNoChunk.exe) and drag the chunk file onto the window as instructed.
