Hold the Command key to open a folder in a new window

You can open a folder in a new window by holding down the Command key when you click on it. This is a really useful tip if you’re trying to copy files from inside one folder to another, just open the directories side by side and copy away!

this is so useful, why didn’t I know about this? so many hidden gems on the mac
cmd+N to open new window
cmd+W to close window
cmd+Q to quit app
i dont get it. explain more please
@mark, if you are in the finder and you want to open a new finder window you hold down the command key and a new window spawns from the old window
Actually, it’s a double-click. At least for me.
