X File Explorer (Xfe)
X File Explorer (Xfe) is an MS-Explorer or commander-like file manager for X. It is based on the popular, but discontinued, X Win Commander, originally developed by Maxim Baranov. Xfe is developed in 2002 by Roland Baudin, a french Linux enthusiast. Why another file manager when many excellent choices exist already? Why not use a full-blown, animated, bells-and-whistles file manager like Konqueror, Nautilus, or Rox? Although all these file managers are feature rich and cleverly designed, let's face it, they are huge! If you're a console addict, a light desktop user, or have an older system, resource-hogging file managers just aren't the way to go. Especially since most file managers are Desktop dependent (KDE, Gnome, Xfce, etc.), requiring you to load all kinds of unwanted bloat onto your system. Xfe is small, very fast, and only requires the FOX library to be fully functional. Plus, it can be launched from the command line in a fraction of a second.

4Pane
4Pane is a multi-pane, detailed-list file manager for Linux. It is designed to be fully featured without the 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. As you can see from the Screenshots its display is split into a left directory tree-view, and a right detailed-list view which by default shows both files and directories. There are normally two of these twin panes displayed (thus the name) but this, and almost everything else, can be configured to suit your needs. It has been built and tested on all the main Linux distros, using both current and older versions. Though it has a gtk-style appearance, it's not tied to any particular desktop.
