Use These Settings to Show or Hide Filename Extensions

On the Mac, nearly every file has an extension, a set of characters after a period that indicates what type of file it is and determines which app opens it. So, .png indicates a PNG graphic that opens in Preview by default, .pages denotes a Pages document, and .docx identifies a file as belonging to and opening in Microsoft Word. Plus, the extension for all applications is .app. Depending on what you do, how often you exchange files with people on other platforms, and your personal preference, you may wish to see more or fewer extensions. You control that in Finder > Preferences > Advanced, with the “Show all filename extensions” checkbox. Individual files can override the setting, so if an extension isn’t doing what you want, select the file, choose File > Get Info, and check or uncheck the Hide Extension checkbox in the Info window.
