A file explorer is a software application that allows users to navigate and manage files and folders on their computer or device. It provides a graphical interface where users can view, open, copy, move, or delete files. Common features include search functionality, file previews, and the ability to create new folders. Most operating systems, such as Windows and macOS, come with built-in file explorers, like File Explorer for Windows and Finder for macOS. These tools help users organize their digital content efficiently, making it easier to access important documents, images, and other files.
