Friend of mine would like a GUI file manager. He doesn't like Konqueror. Anything else? I remember a discussion about that topic a while ago.
xwc (XWinCommander) is interesting (I don't use it extensively, but rather liked it).
I like Gnome Midnight Commander the best. (gmc)
XWin Commander is pretty much an Explorer clone so if your friend likes the Windoze type file manager, it would be a good choice. File Runner is nice, though not really pretty.
I like Midnight Commander, which is not GUI, but which has all the features, and more, of the GUI file managers. Have them try it out too, they may like it.
