Epson 386/25 Manuel D’Utilisation

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 diskette before you
format it. See your MS-DOS Reference Manual 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 diskettes and the

original Reference and Utility diskettes that came with your

computer. Then use only the copies. Store the original diskettes

in a safe place away from your working diskettes. Also, copy your

data diskettes regularly, whenever you revise them (to keep

them up-to-date) 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:

❏ 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.
