4Pane is a four pane detailed-list file manager
for Linux. It is designed to be fully-featured
without bloat, and aims for speed rather than
visual effects. In addition to standard file
manager things, 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.
