Apología, after signing up and verified, it was not easy to get back to the exact spot that folks were using. Since you are the Guru for the excellent dupeGuru, I perhaps left my message to you. Again, a thousand pardons on form. Moving from Win to Linux over the last three years. I had hoped to stop always having to have recourse back to Windows 10 simply because some very good programs work there with no better alternatives in Linux. I am not yet competent to rewrite code, recompile and all those other lovely crafts. I simply want to get jobs done. Work that gets paid. My clients really don't care what kind of pencil or software I use. MS doesn't really care either. Canonical does not know me either. I respect them all. Only in the Linux world is one endlessly asked to get into the wondrous craftsmanship when instead of becoming a carpenter one simply wants comfortable functional furniture. So there is this GREAT software that was born in Linux, and today works well in Windows 10, but NOT in the current world of Linux. SAD. Ah but WAIT! Is there better than dupeGuru for Linux? No. So the Linux open software movement certainly produces pearls but that marvel sometimes throws away diamonds. I use Linux because I admire its Erector Set nature to cut an excellent OS down to highly efficient and tailor it to a purpose. Sometimes I need a special utility like dupeGuru to reform clients files. I'm big into cluster systems that use little Linux systems to grind away at large data sets. Linux can be configured to not choke at such tasks. Windows is a different environment. But dupeGuru "just works" there, but not at all in its birthplace. Of course, from admiration that is frustratingly sad. No, I have deliverables to clients. So no, haven't responsibly the time to find the right compiler and learn how to make the results work in a large cluster. So we do what we have to do with just a few very powerful Win PCs then leave many orders of magnitude larger processing to our Linux clusters. I admire what you do. Nothing better than that but we solve client problems. I don't expect you to think of folks like us as your clients. That's OK. All the best, David
