Navigating in CHILDES with DOS is just like navigating on any other DOS disk. Files are located in directories, which may be embedded under other directories. The top-most directory is known as the "root" directory. The following outline shows, in part, the location of the files on Adam, Eve, and Sarah:

>MSDOS
    >database
        >english
            >brown
                >adam
                    (files)
                >eve
                    (files)
                >sarah
                    (files)

To go up or down in directories, type the "cd" command.  For example, to go down into the "brown" directory from the "root" directory, type the following command:

cd brown <enter>

To go down from there into Eve's data, type the following command:

cd eve <enter>

To go up one directory from any level in DOS, type the following command:

cd .. <enter>

To observe your current position in the system directory, type the "dir" command:

dir <enter>
