If you no longer need a directory, you can remove it with the

RMDIR command (which can be abbreviated RD). Before

removing a directory, you must delete any files it contains or

move them to a different directory. You can only delete a

directory that is empty. (To delete files from a directory, use the

DEL or ERASE command. See “Deleting Data,” below.)

To delete an empty directory, such as the ACCOUNTS

directory under LEDGER, type the following and press Enter:

Before you can store data on a new diskette, you must format it.

Formatting prepares the diskette so that MS-DOS can store

data on it. You need to do this before you use the diskette for

the first time.

You can also reformat previously used diskettes. This process

erases all data on the diskette. Always be sure you no longer

need any files on a diskette before reformatting it.

You can format two kinds of 3 

 diskettes. Double-sided,

double-density diskettes can be formatted to hold 720KB of

data. Double-sided, high-density diskettes can be formatted to

hold 1.44MB. Ordinarily you may prefer to use high-density

diskettes, because they hold more information. But if you need

to transfer files to another computer that cannot read 1.44MB

diskettes, you can purchase double-density diskettes and use the

720KB format.
