When we found Medieval Software's new app called Dual File Manager XT yesterday, we jumped on it right away due to its 2-pane support. Ever since the '90s, 2-pane "orthodox" file managers like the Midnight, Norton, Volkov, and most recently Total Commander have been an absolute necessity on any computer I use.
In fact, once I install a Windows OS nowadays, Total Commander is the first program that follows. Those who try 2-pane file managers can't (or rather shouldn't want to) go back to the conventional Explorer-style layouts - the level of productivity they bring is unparalleled.
