I understand both sides. I was using a pirated DO6 or 7 back in the day, i cant remember now exactly. I couldnt afford to buy it, i did not have a job, i was a student, so i had to be careful where to spend that extra. I was thinking who the hell would pay that money? But time went on, i got a decent job, my first payment came in and i bought a student windows licence, AND a DOpus licence in 2014. Since then all my work went smoother, i got wiser (hopefully). The dudes at GPsoft give you so many support, the application itself is ever-expanding, so i came to realise that the price i payed for this was totally worth it. I love DOpus, if you are a user who uses a filemanager every day for hours, i say if you buy DO your everyday life will get better, less frustrating. So the price is 89AUD, (in my country its 18000HUF, its a lot,it was nearly 1/6th of a one month paymant for me, so i can feel your pain @SKerrigan). Yeah, its not the cheapest software, but itself, and the crew behind it are working hard, and it has a price. If i called you to do some work for me and you made it and i was like: ah man i dont have money could i pay less? Then your motivation would decrease and your work for me will be cheaper in quality because you would feel i dont deserve your best efforts.
So all i can say, looking back from today, its totally worth it. This is the most premium File manager software you can buy on earth right now. Trust me, i tried all of them. From DOS Navigator to Total Commander. Nothing comes close. So please try to get some spare coins and buy a Single PRO licence, you will feel the quality and the devs will feel the motivation to improve DOpus.
These are my thoughts, sorry for the wall of text!
