I'm also more familiar with the excellent XYplorer.

I could not find any in depth comparison with Directory Opus. These two have accumulated so much features over the years, it became a kind of expertise to know them in detail.

The chance of a dual-expert willing to clearly expand on his experience is small. I wish more tech journalism was on this level. Instead, the verge had (at least) 4 articles in 2022 on windows explorer getting... tabs.

Disclaimer: Last I checked was over 10 years ago, so it’s very possible this information is wrong by now.

It doesn’t support dual tree + dual pane (so two explorer trees location synced to their respective pane), by far my favorite DO view.

Locked folders allowing changes. I have some frequently used folders as tabs, and set them to "locked, allow changes", which makes it, so they behave like normal tabs, but once I switch tabs, they revert to their base directory again.
