Before you can store data on a new diskette, you must format
it using the FORMAT command. Formatting prepares the
diskette so that MS-DOS can write data on it. You need to do
this only once, before you use the diskette for the first time.
You can also reformat previously used diskettes to store new
data. This process erases all the data on the diskette, so be
sure you do not want to save any of the files on a used
diskette before you format it. See your MS-DOS manuals for
instructions on using the FORMAT command.

It is important to make copies of all your data and system
diskettes. Make backup (or working) copies of all diskettes
that contain programs, such as your MS-DOS, Reference, and
Utility diskettes; then use only the copies. Store the original
diskettes away from your working diskettes. Also, copy your
data diskettes regularly, whenever you revise them and store
them away from your originals.
If you have a hard disk, you’ll probably use it to store the
programs and data files you use regularly. Keep backup copies
of all your files on diskettes.
You can copy your data in several ways. See your MS-DOS
manuals for instructions on using the following commands:
You can use the COPY or XCOPY command to copy
individual files or groups of files.
You can use the DISKCOPY command to make an exact
duplicate of a diskette.
You can use the BACKUP command to back up hard disk
files to diskettes. Because BACKUP can split large files
across two or more diskettes, it makes more efficient use
of diskette space than COPY or XCOPY.
