If you never try it, wine it

Have you looked at the KDE application krusader or the "Midnight Commander" (mc). You didn't say which desktop system you use, but I think the the default editors in both GNOME (gedit) and KDE (konqueror) have "commander" modes available.

"FAR manager" is better than mc or total commander. Isn't ported to linux, unfortunately..

krusader is rather different than ghisler. gnome is closer rather

i like gvim for a gui

mc doesn't have all the "bells and whistles" of other "commander" style file managers, but it does have one big advantage: it runs quite well in a TTY without anything more than ASCII display controls, and it's much easier to use (but less versatile) than emacs. I always install mc so it's available when /etc/X1/xorg.conf is messed up or fsck barfs during the boot-up device check, etc.

But that's perhaps a bit off-topic.

looks like mc, here shots: http://www.farmanager.com/screenshots.php?l=en

It looks like mc (which looks like "norton commander"), but it's better done believe me. There are many "commanders" with similar interface: "volkov commander" (64kB com file for MS-DOS), something like "dos navigatore", etc. FAR (btw it is OpenSource now) has better gui and keyboard navigation, plus easily extensible (you can add your own encoding, macros, bind it to key, etc.). What I hate about mc is it's ugly interface, not-well-designed dialog boxes (many dialogs have "skip all" option missing, or have awkwardly assigned hotkeys), weak help system, the ugly habit of printing stdout/stderr contents over screen, and messages "command still running" (while it isn't). Unfortunately, I don't know any better Linux alternative to FAR, so I'm using mc, although I don't like it. Porting FAR to Linux will be a problem - it's heavily dependant on Windows API (works through wine, but you can't resize window this way, and can't run linux commands). Of course FAR had its own problems (unicode characters wouldn't show in Windows console), but its GUI (or "TUI") design and usability is superior to mc.
I really hope someone someday will implement better cross-platform "norton commander" clone for Linux (using FAR as a reference). Maybe one day I'll start creating something like this myself, but even if it will ever happen, it isn't going to happen very soon.
Sorry, I always thought that using non-text-based software for file navigators was a bad idea (bad performance, slow navigation, focus problems, etc.), and I'm not going to chance opinion any time soon. Even on good machine (dualcore with good amount of RAM) such programs normally don't allow me to work as fast as I could with FAR.
