I think I am more prone still to use them because they remind me of Dir(ectory)Opus on Amiga.
On DOS Norton Commander was tool of choice.
As for DOS version of LaunchBox, I wonder if Jason will add other emulator support, turning it into great tool for emulation on my old PC, that is currently boxed in garage due to pcem and other emulators. With last move I got rid of Pentium 100, but still have bunch of old laptops, 2 x P2 - 450Mhz end bunch of newer computers.
