Sometimes our projects get cluttered with assets that are not being used in-game, but we cannot really delete them because retrieving them can be difficult if they are needed later on. Use this package on the release branch of your project to remove any unnecessary assets. This project only deletes assets specifically marked for deletion.
You can mark assets for deletion by attaching the UnusedAsset script to them.
Then you can run Tools/Purge Unused Assets/Purge Assets to delete the assets.
