Computers use hierarchalsystems that go from general information in directories to specificinformation in subdirectories. Carefully plan the organization of informationon disks and hard drives.Directories orDirectory files are groups of files that are extensions of the list file. Thefilesmain file or directory, called the. root directory or parent directory, isdistinguished by a backslash (\).
