I tend to do a lot of file management from the shell (
zsh, in my case); this
is very flexible / powerful and so on. But, for some things a bit more
graphical approach is nicer.
There are fully graphical file-managers like Nautilus or Thunar, but for a bit more keyboard-friendly file-management, there are so-called orthodox file managers - the archetypical Norton Commander and its descendants, like midnight-commander (mc) and gnome commander.
Not surprisingly, emacs has its own incarnation - it is called the sunrise commander and happily it's obtainable through ELPA. It's become an important of my workflow. When you're used to Midnight Commander, you'll feel right at home.
If you want to use
emacs for yet another of your computer-based
activities, give it a try.
