Quickly Toggle Hidden Files/Folders in Finder 25th July 2018 I’ve just come across a rather helpful tip on Reddit, and it’s a simple key combination to toggle hidden files and folders in Finder. It’s just: CMD + SHIFT + . It also works in the Open/Save dialog windows. Via u/CompiledSanity on Reddit. Leave a Reply Cancel reply Your email address will not be published.
