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!

Since switching hosts (I hope you are alright, Ed! Wherever you are …) quite a few things seems to be wonky.

Juggling two energetic boys (of very different ages) on Coronavirus lockdown, I'm unlikely to have them all fixed any time soon. Mail me! to prioritise!
