Epson 20 - Manual (Page 86)

An easy way to copy a group of files is by using wildcard characters in
the filenames. You can use 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, type the following and press
Enter:
__
COPY A:MEMO? B:
You can also use the COPY command 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
Renaming Files
You can use the RENAME command to change the name of a file or
group of files on the same disk and directory. For example, to rename
a file named PROSPECT (in the default directory) to CLIENT, type
the following and press Enter:
RENAME PROSPECT CLIENT
You can shorten the RENAME command to REN. To change the
name of a file from HAMMERS to WRENCHES, therefore, you can
type the following and press
Enter:
REN HAMMERS WRENCHES
