Epson LT - 286e - Manual (Page 86)

If you want to copy this file from the diskette in drive A to the
hard disk but want to change the name of the copy from
REPORT to FACTS, type this command and press Enter:
COPY A:REPORT C:FACTS
To make a copy of this file on the diskette in drive A and assign
the name FACTS to the copy, type the following and press
Enter:
COPY A:REPORT A:FACTS
In this case, you must assign a new name to the copy, because
MS-DOS does not allow two files in the same directory to have
the same name.
For any of the previous examples, if you omit the drive identifier
(A: or C:), the COPY command uses the current drive. For
example, if the current drive is C and you want to copy the file
REPORT from drive A to drive C without changing the
filename, enter the command as follows:
COPY A:REPORT
MS-DOS writes the copy to drive C because drive C is the
current drive. You can save a few keystrokes by omitting the
drive identifier of the current drive, but it is equally correct to
include all the drive identifiers.
You can use wildcard characters to copy a group of files at one
time. A wildcard character stands for some other single
character or group of characters in the filenames. MS-DOS
recognizes two wildcard characters: * and ?. The asterisk
represents any group of characters and the question mark
represents any single character.
