Unused Asset Cleaner

Unused Asset Cleaner is a powerful and safe utility for Unity Editor that helps you identify, quarantine, and permanently delete unused assets in your project to keep your project size small and compile times fast. Features include Smart Dependency Scanning that automatically identifies assets not referenced by any scenes in Build Settings or global Resources folder, Code Reference Detection that prevents accidental deletion of dynamically loaded classes, Non-Build Scene Warnings that highlight assets used only in test scenes, Quarantine System that safely moves unused assets to a hidden backup folder for easy restoration, Exclusion List for marking false positives, Empty Folder Cleanup, and Filtering and Sorting options by size, name, or category. To start cleaning, right-click on any folder in your Project window and select Quick Setup > Clean Unused Assets Here. Once the scan is complete, review the results, then choose to Move to Quarantine or Delete Permanently. Quarantined files can be restored to their original locations at any time.
