In macOS Catalina 10.15.4, I would like to create a new folder in Finder, in the view where directories in Finder are organised with the second button from the left ("Show items as icons, in a list, in columns or in a gallery). Specifically, I would like to create a new folder inside a specific existing folder (let's call it "Folder X"). But I don't know how to do this.
What I have tried, is to highlight Folder X, then click on the "cog" button, and then select "New Folder". However, this just creates a new folder at the root of all the displayed folders. It does not create a new folder inside Folder X, even though Folder X is highlighted. So, the only way I know to do this, is to create the folder as above, and then drag it into Folder X. This seems very inefficient, and there must be a way to directly create a folder in Folder X.
How can I do this?
