Directories and Subdirectories
Data stored on disks requires a system of retrieval. Computers use hierarchal
systems that go from general information in directories to specific
information in subdirectories. Carefully plan the organization of information
on disks and hard drives.
Directory files are groups of files that are extensions of the list file. The
main file or directory, called the. root directory or parent directory, is
distinguished by a backslash (\). Other directories have file names followed
by the abbreviation dir and are sometimes called child directories.
Directories are limited in the number of files they can hold, which
necessitates creating subdirectories.
Figure 8-19 shows directories or files of general data.
