What are the Features of file management system?

Answer 1

The following features define the class of orthodox file managers.

• They present the user with a two-panel directory view consisting of one active and one passive panel. The latter always serves as a target for file operations. Panels are shrinkable and if shrunk they expose the terminal window hidden behind them. Normally only the last line of the terminal window (the command line) is visible.
• They provide close integration with an underlying OS shell via command line and associated terminal window that permits viewing the results of executing the shell command entered on the command line (e.g., via Ctrl-O shortcut in Norton Commander).
• They provide the user with extensive keyboard shortcuts.
• The file manager can be used without or with minimal use of the mouse.
• Users can create their own file associations and scripts that are invoked for certain file types and organize these scripts into a hierarchical tree (e.g., as a user script library or user menu)[citation needed].
• Users can extend the functionality of the manager via so called User menu or Start menu and extensions menu. Norton Commander introduced the concept of user-defined file associations that is now used in all modern file managers[citation needed].

Other common features include:

• Information on the "active" and "passive" panels may be used for constructing commands on the command line. Examples include current file, path to left panel, path to right panel, etc.
• They provide a built-in viewer for (at least) the most basic file types.
• They have a built-in editor. In many cases, the editor can extract certain elements of the panels into the text being edited.
• Many support virtual file systems (VFS) such as viewing compressed archives, or via an FTP connection.
• They often have the word commander in the name.
