New Mac app from Martin Lexow, the developer behind App Ahead (which offers a slew of good and intriguing Mac apps):Preview folder and archive contents (ZIP, RAR, and more) instantly in macOS Quick Look. Just select a folder and press the Space bar.It’s just that simple. Install it from the Mac App Store — free of charge — and you can Quick Look inside archives and folders. Looks, feels, and works like a feature that ought to be built into the Finder itself. Cool.
