Changing the default drive

To change the default drive, type the letter of the drive you
want to change to, followed by a colon. Then press Enter. For
example, to change the default from A to C, type the following
and press Enter:

C:

MS-DOS acknowledges the change by displaying the command
prompt

C>.

Changing to a new drive is also called logging onto

that drive.

Specifying the drive designator

If you want to access a program or file on another drive without

first changing the default drive, type the drive designator along
with the filename. For example, if you are logged onto drive A
and want to use a file named PROGRAM on drive B, you

would type the following:

B:PROGRAM

MS-DOS loads and executes the file named PROGRAM from

drive B, but stays logged onto drive A.

Types of MS-DOS Commands

Each MS-DOS command is either internal or external. Internal

commands are commands that are built into

MS-DOS and can

he used at any time once

MS-DOS is loaded into memory.

External commands are stored on your system diskettes as

program files.

If you display a directory of the files on your MS-DOS

diskettes, you see the names of the external commands but not

the internal ones. The following lists show which external
commands are on which diskette.
