Epson 386SX - Manual (Page 108)

To copy the file named REPORT to the same drive or directory
and name the copy FACTS, type the following and press Enter:
COPY REPORT FACTS
Now you have two files on the current 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 current drive.
You can use wildcard characters to copy a group of files. There
are two wildcard characters: * 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
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 (such as MEMO1),
type the following and press Enter:
COPY A:MEMO? B:
You can also use the COPY command to combine several 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
Now the file DATA consists of REPORT followed by FACTS
followed by MEMO.
