Chapter 6 / Command Reference
If you omit the /A and!B switches, MS-DOS uses /B. Notice that
this default is the opposite of that for the COPY/APPEND and
COPY/COMBINE commands.
N
tells MS-DOS to verify that the sectors written to the disk
are recorded properly. This parameter slows the process because
MS-DOS must check each entry recorded on the disk.
Notes and Suggestions
• By varying the syntax of COPY slightly, you can also use it
to:
• Append one or more files to the end of an existing file,
keeping the target file's filename.
• Combine files into a new file that has a unique filename.
(See COPY/APPEND and COPY/COMBINE for more informa-
tion on these uses of COPY.)
• Use the /B parameter with a target file to remove the EOF
character from the end of the file. Some application programs
require that the EOF character not be included.
• Use COpy to:
• Copy a file to another disk: COPY lets you make backup
copies of files to protect important information.
• Transfer external commands to another disk: When you
receive your system disk, all external commands are in the
root directory. (Some of the Version 3.2 external commands
and system utility files are on the Supplemental Programs
diskette.) Tailor your directory structure to your own needs
by moving some of these commands to their own directory.
• You cannot copy a file onto itself. (You cannot copy it to the
same directory, giving it the same name.)
copy b:memos b:memoslENTERI
will cause an error message. This command:
copy memos
I
ENTER
I
will also cause an error message. You are trying to copy the
file Memos that is in the current directory to another file
Memos, also in the current directory.
