I've done things that people thought were magic. It was TC. There are about twenty similar programs, all descended from the Norton Commander. Any one of them is enormously better than the file managers that come with most OSs, especially windows. Ive read estimates that say you're about four times as productive if you use on, and I think that may be very conservative. There are a lot of things you can't do without on…
I duuno mate, I find the MacOS but especially the default Gnome file manager to be much more limited than the latest Windows Explorer in functionality. Gnome Files is a joke really, feels more like something on a mobile device.
The thing is, file managers that come with mainstream OSs are not designed to appease power users, as they will install their own personal favorite one anyway, but to make life easy for the average joe who doesn't know much about computers, files, extensions, etc. That's why they're so simplistic out of the box.
Something like TC, would be really confusing for the user who just wants to view the best photos in the download folder and drag and drop them to the Gmail in Chrome.
Trying to appease power users is an exercise in futility anyway, no matter what you do, someone will cry that his favorite and most used feature is still missing, so most SW companies don't even bother anymore with the tiny power-user market share if they also aren't paying customers. TC is one of the few exceptions that survived by including everything and the kitchen sink.
HN users should learn to detach themselves form the power-user mentality and empathize with the average joe who isn't tech savvy and has no interest in becoming tech savvy as they have other hobbies than learning how their computer works under the hood and becoming 40% more efficient with their file-management-fu.
