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.
