Note
MS-DOS provides several commands that make using
pathnames easier:
APPEND lets you set a search path for data files and
executable files so MS-DOS knows where to find them
even if you don’t specify the drive and directory.
PATH lets you specify a search path for commands and
program files so you don’t have to type a full pathname
every time you want to run an application program or an
MS-DOS command.
SUBST lets you substitute a drive letter for a directory
path, which is convenient if you frequently type long
pathnames.
See your MS-DOS Reference Manual for information on
these helpful commands.
Creating Directories
You use the MKDIR command to create directories in
MS-DOS. For example, to create a LEDGER directory under
your root directory, type the following and press Enter:
MKDIR \
LED
G
ER
You can abbreviate the name of this command to MD. For
example, to create a SALES directory under the LEDGER
directory, type the following and press
Enter:
MD \L
E D
G
E R
\
S A L E S
If you are currently in the LEDGER directory, you could create
the SALES subdirectory with this command:
MD SALES
In this case, you do not need to specify the path to the
LEDGER directory because it is the default directory.
