Epson 20020 Manuel D’Utilisation

At any given time, MS-DOS considers one disk drive to be the
default drive. The default drive is the one on which MS-DOS

executes your next command, unless you tell it to do otherwise.

For example, if the default drive is C, and you issue the DIR

(directory) command, MS-DOS lists the files stored on drive

C. If the default drive is A and you type 

WP 

and press 

Enter,

MS-DOS looks on the diskette in drive A for a file called WP
and executes it.

The MS-DOS command prompt tells you which drive is the

current default. The command prompt consists of the drive

letter followed by a greater-than symbol, "<". (Depending on

how your system has been set up, the command prompt may

also include additional information.) Thus, when you see A>
displayed on your screen, you know that the default drive is A.

The command prompt also lets you know that MS-DOS is

ready to receive a command from you.

If you need to access a file or program on another drive, you

can either change the default drive or specify the other drive
when you give the command.

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:

MS-DOS acknowledges the change by displaying the command

prompt 

C 

: \>. Changing to a new drive is also called logging

onto that drive.
