old dos commands: dn up?
These two commands were NOT part of dos, but I ran a utility that installed them as DOS commands. In CMD.EXE (the DOS prompt screen) UP moved up one directory. DN moved down one directory. If there were more than one folder, it would list the folders and then prompt user to select one.
Where can I find this utility???? It may have been developed in the 1980s.
These were not *.bat files, they were actual commands that I have installed in ALL of my computers. But I just don' remember how I did it. This is my first new computer in four years.
