Copying Data
It is very important to keep backup diskettes containing copies of
the files you create. You can copy data and program files several
ways:
l
You can use the DISKCOPY command to make an exact
duplicate of a diskette
l
You can use the COPY command to copy individual files
l
You can use the BACKUP command to back up the files on a
hard disk or diskette in a special format.
The COPY command is easier to use when you have only a few files
to back up. The BACKUP command has some advantages when
you want to back up many files at once.
Note
An easy way to perform the functions listed above is through the
MENU
and
XTREE programs. See
the sections
on MENU
and
XTREE later in this chapter. You can also use the MS-DOS
XCOPY command to copy whole subdirectories of fifes; see your
MS-DOS manual for details.
Using the DISKCOPY Command
The DISKCOPY command lets you copy an exact image of one
diskette onto another diskette. The two diskettes must be of the
same size and type; that is, you cannot use DISKCOPY to copy
data from a 3 1/2-inch diskette onto a 5 1/2-inch diskette or to copy
data from a 1.44MB diskette to a 720KB diskette. You also cannot
use DISKCOPY to copy data between a hard disk and a diskette.
To use DISKCOPY, follow these steps:
1. Make sure your original diskette (the one you are copying from)
is write-protected. (See Chapter 4 for instructions.)
