Duplicate Cleaner is an advanced, editor-friendly utility that scans your Unity project for duplicate assets based on customizable criteria. It helps you optimize project size, improve organization, and prevent accidental reference errors. The tool is designed to work entirely in the Unity Editor and is lightweight and efficient, with no performance impact.
Key Features:
- Customizable Matching Criteria: Tailor the detection process to your project by matching by name, file size, created/modified date, GUID, meta file content, file hash, or file type.
- Preview Before You Act: Visualize all duplicates with grouped asset sets, image/audio previews, file size and date info, and sorting, searching, and checkbox-based selection.
- Safe Deletion with Quarantine: Deleted files are moved to a safe Quarantine Folder, and you can instantly Undo Last Deletion or Clear Quarantine anytime.
