Today’s video is how to hide files and folders within Finder. By using the chmod terminal command you can hide any files and folder. This will not delete the file or folder, it will just ensure that it doesn’t show up within Finder. You can hide any document you want and you will not be able to see it. You will however still be able to use it. It is a way of obscuring files from view so they don’t keep up if any one snoops around on your Mac.
