What is the difference between the free version and the registered...

The free version handles everyday cleaning -- temporary files, browser caches, system junk, and privacy traces. It also scans for duplicate files and shows you exactly how much space they waste.

Registration unlocks these additional features:

• Duplicate File Cleaning -- Remove the duplicate files the scanner already found (most users recover 5-50 GB)
• Scheduled Automatic Cleaning -- Daily, weekly, or monthly cleaning on autopilot
• Cleaning Profiles -- Save and switch between named configurations like "Quick Clean" or "Deep Privacy Clean"
• Custom Cleaner Rules -- Define your own file and folder targets using patterns
• Secure File Shredding -- Overwrite deleted files so they cannot be recovered (1-pass or 3-pass)
• HTML/PDF Cleaning Reports -- Export reports for IT documentation or compliance
• Splash-Free Exit -- The brief closing splash screen is removed

Every license tier unlocks the same features. There are no "Pro" vs "Premium" confusion levels. See the RJL System Cleaner">product page for the full feature comparison.
