Introduction

Section 3 introduced you to the Dir command. You used it to display a list of filenames. This section provides more information about filenames and disk directories, sometimes called file paths.

Filenames are given to text, data, and program files that reside on a disk. Directory (or path) names are also given to disk directories, which are convenient subdivisions in which categories or families of files may te collected and maintained. Several commands are available to create, list, or delete filenames and directory names. These include:
MKDIR (or MD)            Make (or create a new sub directory.

CHDIR (or CD)            Change to (or log) a named directory.

Filenames

It is important to understand DOS file naming conventions and their use. Here, filenames and some special filename "tools" called wild cards and literals are described. What is a File name?   Every program and data file is given a name to differentiate it from other programs and data files. A program is one or more computer instructions collected into a file. A data file is normally a collection of characters (or data) that make up a document, like a letter, or a database, like a collection of accounting transactions or customer records. Descriptive filenames are normally used. For example, if you create and save a letter to Mom, you might give it the filename MOM.LTR. A letter to Dad could be called DAD.LTR. A word processing program file might have the filename WP.COM. Examine these filenames a little closer. First, notice that each filename is meaningful. This is important if you want to know what is in a file by looking at its name. Obscure filenames are of little u

What Is DOS?

What is DOS? Your disk operating system (DOS) performs a number of essential jobs. These includes: Controlling the way various application programs, such as word processors, electronic worksheets, database managers, accounting programs, etc., operate with your computer. DOS creates an environment that lets these programs "talks" to your computer and its input and output devices (printers, modems, display screen, keyboard, disk drivers, etc.). Keyboard and program-generated information is read, interpreted by DOS, and transferred to the selected computer device. Data being returned by your computer device. Data being returned by your computer is again translated by DOS into useful information and written to an output device, such as your display screen, printer, or disk. Providing "housekeeping" and file management utilities that perform useful tasks such as: Disk preparation (formatting, copying, etc.) File operation (creating, displaying, copying, combining, renami
