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 copying, moving, deleting, and renaming files. Common examples of file managers include Windows File Explorer and macOS Finder. File managers often include features like search functions, file previews, and the ability to create new folders. They can also support various file formats and allow users to connect to cloud storage services, making it easier to manage files across different locations and devices.
