Now you have two files on the default drive that have the same
contents but different names. In this example, you can omit the
drive designators because the original file and the copy are both
on the default drive.
Using wildcards
An easy way to copy a group of files is by using wildcard
characters in the filenames. You can use two wildcards:
* and ?. The asterisk represents any group of characters and
the question mark represents any single character.
For example, to copy all the files on the diskette in drive A to
drive C, type the following and press
COPY A:*.* C:
To copy all files with names that begin with the four letters
MEMO and end with any single character (such as MEMO1),
type the following and press
COPY A:MEMO? C:
You can also use the COPY command to combine several files
into one. For example, to create a new file called DATA that
consists of the files REPORT, FACTS, and MEMO, type the
following and press
COPY REPORT + FACTS + MEMO DATA
Now the file DATA consists of REPORT followed by FACTS
followed by MEMO. Because the files are located on the
current drive, no drive designators are necessary.
To copy REPORT, FACTS, and MEMO from drive A to the
file named DATA on drive C, type the following and press
Enter:
COPY A:REPORT + A:FACTS + A:MEMO C:DATA
