This script was created for Mafia: Definitive Edition but works with Mafia III: Definitive Edition as they share the same audio folder structure.

How It Works:

1. Extract the downloaded zip archive to a convenient location on your computer.

2. Navigate to your game's root installation directory.

`Go to the Steam library, right-click on Mafia III: Definitive Edition, go to "Manage", then click on "Browse local files"`

3. Copy the extracted file into your game's root directory.

4. Run the script (00 Reduce Game Size.bat).

5. Follow the on-screen instructions to select the language you wish to keep.

Source Code:

00 Reduce Game Size.bat
