Still, can't imagine computing without that Powerdesk explorer GUI.
PowerDesk was my first proper Explorer replacement; can't remember what version, but it was before VCom. Ontrack, wasn't it? Anyway, I too really liked it.
Then they (Vcom, that is) broke something and professed absolutely no willingness to mend it again. (It was something important to me but clearly not to them -- might have been .dbf viewing, might have been the synch tool, I can't remember now.) To say their support leaves something to be desired is about the most generous a statement I can imagine.
I played with a variety of desperately inadequate alternatives for a while. Then (cue sound of heavenly choir) I found Directory Opus.
Then, more recently, I found XYPlorer. (I like it quite a bit more than Opus for portable use, although the learning curve is perhaps a bit steeper, and I’d had it for quite a while before I started discovering its true power.)
Both of those two are so much better than Windows Explorer it'd make your head spin. And I don't even remember why I was so impressed with PowerDesk anymore, back in the day.
I’m completely aware that YMMV applies here in spades
but I’d be interested to know if your preference for PowerDesk is just about familiarity, or if it genuinely has acquired functionality or something ergonomic that gives it an edge over the other (increasingly extensive!) non-Microsoft competition.
(And it’s okay if it seems stupid but marvellously great -- like, I think the ability to double-click on the desktop to open an Opus lister is a tiny bit brilliant, for instance!)
