Directories help keep related files orga-
nized on a disk in a hierarchical, “inverted
tree” structure. Each disk has a “root”
directory; for example, a
C:\> prompt nor-
mally indicates that you are at the root
directory of hard-disk drive C. Additional di-
rectories that branch off of the root directory
are called
subdirectories
. Subdirectories
may contain additional directories branching
