HOW MS-DOS STORES INFORMATION
If you want to learn more about how your operat-
ing system works, you need to know how MS-DOS
organizes and stores information.
About Files
Your computer stores all information on the disk-
ette in files. A file is a collection of information.
These are the main types of files:
System files contain operating system informa-
tion that manages the computer's operations.
Program files contain information that causes
the computer to perform a task or set of tasks.
Data
files contain information you enter, such as
the documents and spreadsheets you create
with software.
About Directories
All files on a diskette reside in directories. A direc-
tory is simply a storage space for your files. When
you format a diskette, you create one directory
called the root directory. On your MS-DOS system
disk, the root directory contains all command and
system files. When you start up your computer
using MS-DOS, you are automatically in (operating
from) the root directory.
