Quick Project Cleaner provides a streamlined interface for removing unused data from your Blender projects to reduce file size. The tool scans your file for unassigned materials, orphaned images, unused meshes, actions, and node groups, allowing you to delete them from a dedicated panel.

The add-on features a dry run mode that lets you preview which items will be deleted before executing the operation. A live data counter displays both total and unused counts for various datablocks directly in the sidebar. Users can toggle specific data types to clean individually or execute a full deep clean leveraging Blender's internal purge functionality.
