Permission settings determine who can view and alter files on the computer. You change permission settings at the bottom of the Info window for a file, folder, or disk in the Finder. For example, you can change permission settings for a folder so that other users who log in to your Mac, or connect to it for file sharing, can view but not change files in a folder.
