I'm a bit confused at why people are saying it isn't updated, as its now a paid Stardock product (officially licensed, according to Sean Werkema's resume):

The Stardock version 3.0 Build 1711 is from 2018, so that is a while since the last update and there's still no HiDPI. There's also a bug where it interprets 0-byte placeholder files as 8GB giants. But 2018 seems to be a newer update than what people here are suggesting.

But v3 isn't free, and I've not tried the old freeware / open source version, so I don't know if newer actually means "better".
