What Holon Clean does

Every feature listed here is available today.

🔍
Unused File Scan
Identifies files in your Canvas course that aren't linked to any page, assignment, module, or discussion — flags files that appear unreferenced; review each result before deleting because Canvas or external references may not be visible.
🗂️
Empty Folder Cleanup
Finds and bulk-deletes empty folders that accumulate after copying or reorganizing a course. Clean your file tree in one click.
📋
Copy Prep Mode
Pre-copy scan that flags orphaned files and empty folders before you duplicate the course — so the copy starts clean.
📊
Scan History & KPIs
Every scan is logged with before/after file counts and storage saved. SVG trend chart shows cleanup progress over time.
🗒️
Activity Log
Full audit trail of every file deleted, every folder removed, and every scan run — sortable and filterable by date and action type.
⚡
Bulk Delete
Select all unused files and delete them in a single operation. No clicking through Canvas's file manager one by one.
