The following sections discuss the basics of creating and using
directories.
Note
The XTREE utility provides a simple way to see and organize
your directories. See the description of XTREE later in this
chapter.
The Default Directory
MS-DOS always recognizes one directory as the default or
current directory, just as it always recognizes one drive as the
default drive. The default directory is the one in which
MS-DOS performs your commands, unless you tell it to do
otherwise.
If you want to run a program or access a data file that is not
stored in the default directory, you can either change
directories (making a different directory the default) or include
a pathname in your command.
Changing the Default Directory
To change from one directory to another, use the CHDIR
command, or its shorthand equivalent, CD. For example, to
change to the root directory of the default drive from anywhere
in the directory tree, type the following and press Enter:
CHDIR \
If you are in the WORDPROC directory and you want to
change to PERSONAL, a subdirectory of WORDPROC, type
the following and press Enter:
CD PERSONAL
