This tool finds unreferenced assets in Unity project.

All code combined into one script for easier portability. So you can just copy-paste DependenciesHunter.cs to your project in any Editor folder.

At first, it calls

AssetDatabase.GetAllAssetPaths()

to form a map of all assets.

Then it uses:

AssetDatabase.GetDependencies

to find dependencies for each of those assets. As a result dependencies map is formed.

Then it simply finds all assets which are not presented as a dependency within this map. Such assets considered as unused if they aren't marked as to be ignored in this analysis (by a list of RegExp patterns).

To enable addressables usage uncomment the first line.

// #define HUNT_ADDRESSABLES

The tool has two ways to use it. Each has a menu option, and an editor window.

..click on "Tools/Dependencies Hunter" option which will open the "AllProjectAssetsReferencesWindow" window.

..select the assets and use a context menu option "Find References in Project". It will open the "SelectedAssetsReferencesWindow" window with the results.

In the Analysis Settings foldout you can set files to be ignored by providing a list of RegExp patterns. You can also uncheck the 'Show Unreferenced Assets Only' toggle to view the list of all your project assets with their references number, files sizes etc.
