What is File Manager?
A file manager is a computer program that provides a user interface to manage files and folders. The most common operations performed on files or groups of files include creating, opening, viewing, playing, editing or printing, renaming, moving or copying, deleting and searching for files, as well as modifying file attributes, properties and file permissions. With file manager folders and files may be displayed in a hierarchical tree based on their directory structure. Some file managers contain features inspired by web browsers, including forward and back navigational buttons.
Few file manager services provide network connectivity via protocols, such as FTP, NFS, SMB or WebDAV. It is achieved by allowing the user to browse for a file server by connecting and accessing the server’s file system like a local file system or by providing its own full client implementations for file server protocols.
