A folder icon is a graphical representation used in computer operating systems to symbolize a directory or a collection of files. It typically resembles a physical folder, often with a tab at the top, and is used to organize and store documents, images, and other types of data. Users can click on the folder icon to open it and view its contents. Folder icons are commonly found on desktop interfaces, such as those in Windows and macOS. They help users navigate their file systems efficiently, allowing for easy access to stored information. Customization options may also allow users to change the appearance of folder icons for better organization.
