For example, to copy all the files on the diskette in drive A to the diskette in
drive B, type the following and press
Enter:
COPY A:*.* B:
To copy all files with names that begin with the four letters MEMO and end
with any single character, type the following and press
Enter:
COPY A:MEMO? B:
Another task you can perform with the COPY command is to combine a
number of files into one file. For example, to create a new file called DATA
that consists of the files REPORT, FACTS, and MEMO, type the following
and press
Enter:
COPY REPORT + FACTS + MEMO DATA
In the above example, the files are located on the current drive, so no drive
identifiers are necessary. To copy REPORT, FACTS, and MEMO from drive
A to the DATA file on drive B, type the following and press Enter:
COPY A:REPORT + A:FACTS + A:MEMO B:DATA
Using the BACKUP command
The BACKUP command lets you store files in a compressed format for
archive purposes. BACKUP is normally used to back up hard disk files;
however, you can use BACKUP to copy files from any disk to another (hard
disk to diskette, diskette to hard disk, diskette to diskette, and even hard
disk to hard disk).
Unlike DISKCOPY and COPY, which make readable copies of files,
BACKUP creates files that you cannot use until you restore them to the disk
by using the RESTORE command.
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.
