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 \LEDGER

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 \LE DGE R\SALES

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.
