In the old days we had Norton Commander as our powerful 2-pane filemanager for DOS, and MC (Midnight-Commander) ‘which is still a great tool for file management’ for Linux.
Windows Commander, now Total Commander derived from Norton Commander is now an excellent 2pane file manager for Window$.
One of the first things I looked for in Linux, when I started using it, was a filemanager like Total Commander.
The two best 2pane filemanagers are in My opinion Krusader for KDE and GNOME Commander for GNOME and XFCE4 .
Best of all, they are free, have no nag screen like Total Commanders shareware version has, and have the same power.
Yet another reason to switch to Linux
