Can I try RJL System Cleaner before registering?

Yes -- that is exactly how it works. There is no trial period, no time limit, and no feature countdown.

Download RJL System Cleaner for free from RJL System Cleaner and use it as long as you want. Clean your junk files, scan for duplicates, browse the results, and see exactly how much space is wasted.

When -- and only when -- you decide the registered features are worth $19.99, register. There is no pressure, no pop-ups asking you to upgrade, and no fake warnings designed to make you feel like your computer is at risk.

The free version is not a trial. It is the real product. Registration simply makes it better.
