As Reco says: that's a success. You're in a DOS command-line
environment.

New experience: I've never explained DOS commands in terms of
shell commands before; it's always been the other way around.

UNIX systems have a single root; DOS systems have a root on each
filesystem, and filesystems are identified by a letter followed
by a colon. Traditionally A: and B: are removable media and C:
is a hard disk, but it's not mandatory.

Change to a different filesystem root by typing the letter
followed by a colon

        c:

ls      dir         (you want /p for paginate)
cd      chdir       (later versions allow you to substitute cd)
fsck    chkdisk
reset   cls         clear screen
rm      del
cp      copy
cp -r   xcopy       

Go find the executable you need and run it by just typing its
name or its path. Remember the slashes are backwards.
