A file manager is a software application that helps users organize, manage, and access files and folders on their computer or device. It provides a graphical interface that allows users to perform tasks such as creating, deleting, moving, and renaming files. Common examples of file managers include Windows File Explorer and macOS Finder. File managers also enable users to search for specific files, view file properties, and manage storage devices like USB drives and external hard drives. They often include features like file previews and the ability to compress files into formats like ZIP for easier sharing and storage.
