A multi-pane, detailed-list file manager 4Pane is a multi-pane, detailed-list file manager. It is designed to be fully-featured without bloat, and aims for speed rather than visual effects. In addition to standard file manager features, it offers multiple undo and redo of most operations (including deletions), archive management including 'virtual browsing' inside archives, multiple renaming/duplication of files, a terminal emulator and user-defined tools. http://4pane.co.uk
