Dear Jörg, I just want to thank you for this fantastic, bug free and easy to use software. Over the last week I have spent many hours buying three software packages to sort through 60,000 duplicate photo files (all the other software packages would would run for many hours, one run for 18 hours to simply crash and they all cost me together just under $100). Your software took less than two hours cleaned up half the collection with NO MISTAKES. I am so happy to see simple software that simply does the job. I am happy to donate money to you as you saved me many more frustrating hours and maybe more wasted money. Let me know what money would make you happy within reason lol and I will be happy to send to you or if you want a gift or something from Australia simply let me know.

Thanks again, I love the software, Michael
