    How to install disunity and extract assets and bundles from unity games

    This video only concerns the installation of disunity.

    1. Download and install the latest Java JDK for your operating system
    2. Download latest disunity zip here:
    3. Create a folder called disunity on your C drive, and extract content of to this folder.
    4. Download Jcommander and extract it to your desktop.
    5. Navigate to Desktop\jcommander-jcommander-1.47\src\main\java and copy the com folder to the C:\disunity\ folder.
    6. Add C:\disunity\ to your systempath

    Available commands

    Command Purpose

    dump Converts binary object data to human-readable plain text, similar to the binary2text tool shipped with the Unity editor.
    dump-struct Like dump, but just for the structure information.
    extract Extracts asset objects to regular files (.txt, .wav, .tga, etc.). See for a list of supported asset types.
    extract-raw Extracts raw serialized object data. Could be useful for manual extraction if extract doesn't support the wanted asset type.
    extract-txt Like dump, but writes the output to text files instead of the console.
    extract-struct Like extract-txt, but just for the structure information.
    learn Learns the structure information from the submitted files and stores any new structs in the database file structdb.dat. The database is required to deserialize standalone asset files, which usually don't contain any structure information.
    info Outputs various information about assets and asset bundle files.
    info-stats Outputs class usage statistics for asset files.
    bundle-extract Extracts all packed files from asset bundles.
    bundle-inject Injects files previously extracted with the bundle-extract back into the asset bundle.
    bundle-list Lists all files contained in asset bundles.
    split Attempts to split an asset file into multiple smaller asset files.
    list Lists all asset objects in a tabular form.

    Other parameters

    Run disunity with the -h parameter for further usage.

    Yes.. and DisUnity v0.4.0 looks even better, I haven't tested the write functions yet, but I really hope that we will be able to write into assets through command line soon. I would be nice just to have a folder with the extracted asset, and then being able to re import everything after modification

    I got it installed and running, so I will test it this week sometime
