ahhhhhhhhhh...good old Explorer.

Go to its 'screenshots' page and check out the many ways you can set it up to your liking.
I, however, stick with an old 2009 version, which works just fine with Win10. Why? For whatever reason, later versions got rid of my preferred panes configuration. Either that or I'm too dumb to figure out how to implement it. Admittedly, I miss out on a few bell-and-whistles recent versions provide. Most folk will be quite happy with the latest edition.
(We of course shouldn't physically ditch Explorer.)
