This tool finds and/or deletes 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
or add HUNT_ADDRESSABLES to the 'Scripting Define Settings' in PlayerSettings
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.
..click on "Tools/Dependencies Hunter" and then click on Delete Unused Assets
..select the assets and use a context menu option "[DH] Find References in Project". It will open the "SelectedAssetsReferencesWindow" window with the results.
There is also an option "[DH] Find References in Project (Previous Cache)" which will try to use the dependencies database cache from the previous launch and so will perform much faster. This might be useful if for example you want to run multiple analysis without changing assets.

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.
