`The backslash identifies the new directory LEDGER as a sub-
directory of the root directory.
Once you are in the directory, you can directly access any files it
contains.
To change to a subdirectory of the current directory, you do not
need to enter the backslash. For example, to change to the
SALES subdirectory while you are in the LEDGER directory,
type the following and press
CD SALES
To return to the root directory from any subdirectory, type the
following and press
CD \
This command takes you back to the root directory from any
subdirectory.
Using pathnames
You can access files in a different directory by specifying a
pathname. The path consists of a series of directory names
separated by backslashes and the filename you want to access.
The filename is always last and is always preceded by a back-
slash. A backslash at the beginning of a pathname signifies the
root directory; subsequent backslashes separate directory levels.
Normally, MS-DOS begins searching for a file in the current
directory. When you set a path, MS-DOS searches for the file in
all the directories in the designated path.
