> Can you please briefly describe the features you think make it worth it?

If we are talking specifically about windows explorer, I think not freezing randomly for no reason once in a while would be considered a nice feature.

Tons of features packed into 1 small integrated, very fast completely bugless tool done by 1 guy - ie sftp client, best recursive search I've used in Windows (including nested archives), I can view and edit files directly in archives (even within archives) without the need to unpack/repack them, great files / folders comparator, viewer for many formats including hex, open plugin support with good ecosystem, 2-pane system with tabs makes everything much faster and you can keep a lot of parallel work around for later, it remembers them after closing/restart, copying / moving queue is fantastic. You can customize everything. I am barely scratching surface with above. In good ol' Winrar style you can use it perpetually for free as shareware (but damn if somebody deserves money for their tool its this guy).

Once proficient I am much much faster than proficient file explorer users, its not even comparable when one does a lot of things with files/folders, personally and profesionally. By far the best windows-only software I am aware of and the one of main reasons I didnt migrate to Linux. Otherwise I would need 10+ additional software installed and some features of it are best in class (on windows at least).

Its good ol' Norton Commander from DOS alive but has gigatons of modern improvements.

Same. I did not know anything like this existed and I've been tinkering with PCs and building them for 3 decades.
