Once upon a time, there was a operating system called MS-DOS. It was a pretty limited system and awkard to use, but at the same time, it was a lot more useful than the graphical systems built on the DOS. To help the users, many companies created proprietary software that was sold to the end-users.
One of the most popular applications was Norton Commander or simply nc. The first version 1.0 was released as early as in 1986 . This application set the standards for file managers for a long time. In fact, many file managers even today follow the concept of showing files simultaneously in two panels.
In addition to GUI file managers, the command line junkies can use the Midnight Commander, mc. It is available for probably every possible distribution in use. If you like to use Linux on an old computer, you might well try this application that does not steal all the resources of your old computer.
Midnight Commander provides all the usual functionality one expects from a file manager. With it, it is possible to copy, delete, archive, view and edit files or, for example, view man pages, It might not handle everything konqueror handles, but it does well what it is intended to do.
