Folder Preview

I use Quick Look previews with files all the time on my Mac. Folder Preview, a free utility from the makers of Anybox, brings that same utility to folders in the Finder. Once installed, you can preview the contents of a folder simply by selecting it and hitting the spacebar. It’s a handy way to find a file in a subfolder without navigating away from the current folder you’re viewing. Plus, you can select a file in the preview window with your pointer and use the preview’s built-in share button to share a previewed file or folder using any of the share extensions installed on your Mac.
