A file icon is a small graphical representation used on computer systems to indicate a specific file type or program. These icons help users quickly identify and access files, such as documents, images, or applications, by visually distinguishing them from one another. Each file type typically has a unique icon, making it easier to organize and manage files on a computer. File icons are often displayed on the desktop or within file management systems like Windows Explorer or macOS Finder. They can also represent folders, shortcuts, or applications, providing a visual cue that enhances user experience and navigation within the operating system.
