You can use switches with BACKUP to back up files created after
a
certain date or to specify files stored in a certain directory. You can
also tell BACKUP to add only those files that have been modified
since the last time you ran BACKUP. This process speeds up
backup procedures you perform on a regular basis.
For complete instructions on the use of BACKUP and RESTORE,
see your MS-DOS manual.
Note
An easy way to
perform the functions
of the BACKUP,
RESTORE, COPY,
and
DISKCOPY commands is through the
MENU program. See the section on MENU later in this
chapter.
You can also use
the MS-DOS XCOPY command to copy one or
more files; see your MS-DOS manual for derails.
Deleting Data
To delete a file, type
DEL
and then the full name (including the
extension, if any) of the file you wish to delete. For example, to
delete the file named APRIL.TXT from the current directory; you
would
type the following and press
Enter:
DEL APRIL.TXT
You may delete all the files in the current directory at once by
typing the following and pressing
Enter:
DEL *.*
For your protection, when you type
DEL
*.*
MS-DOS asks if
you are sure that is what you want to do. If you are sure, press Y,
then
Enter.
You can also use the ERASE command to delete files. ERASE
works exactly like the DEL command.
