Thank YOU!


..for considering a checksum license. Your support keeps this software (as well as me, my family and hard work) fresh and alive!

You can try checksum at home out for as long as you like, for free. It's the way I like to make all my Windows tools; a business model I believe in strongly. But one that works only with your support..

Welcome to corz.org!

I'm always messing around with the back-end.. See a bug? Wait a minute and try again. Still see a bug? Mail Me!
