A file manager or file browser 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 (e.g. viewing, playing, editing or printing), renaming, moving or copying, deleting and searching for files, as well as modifying file attributes, properties and file permissions. 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. Some file managers provide network connectivity via protocols, such as FTP, NFS, SMB or WebDAV. This is achieved by allowing the user to browse for a file server (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. ==Directory editors== A term that predates the usage of ''file manager'' is ''directory editor''. The first directory editor, DIRED, was invented circa 1974 at the Stanford Artificial Intelligence Lab by Stan Kugell〔(SAILDART Username key for above )〕 A directory editor was written for EXEC 8 at the University of Maryland, and was available to other users at that time. The term was used by other developers, including Jay Lepreau, who wrote the dired program in 1980, which ran on BSD. This was in turn inspired by an older program with the same name running on TOPS-20. Dired inspired other programs, including dired, the editor script (for emacs and similar editors), and ded. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「file manager」の詳細全文を読む スポンサード リンク
