Copies files. See also MOVE, XCOPY and ROBOCOPY.

Examples:

• copy F:\\File.txt

  Copies the file into the current directory, assuming the current directory is not F:\\.

• copy "F:\\My File.txt"

  As above; quotation marks are needed to surround a file with spaces.

• copy F:\\*.txt

  Copies the files located at F:\\ and ending in dot txt into the current directory, assuming the current directory is not F:\\.

• copy F:\\*.txt .

  Does the same as the above command.

• copy File.txt

  Issues an error message, as File.txt cannot be copied over itself.

• copy File1.txt File2.txt

  Copies File1.txt to File2.txt, overwriting File2.txt if confirmed by the user or if run from a batch script.

• copy File.txt "My Directory"

  Copies File.txt into My Directory directory, assuming My Directory exists.

• copy Dir1 Dir2

  Copies all files directly located in directory Dir1 into Dir2, assuming Dir1 and Dir2 are directories. Does not copy files located in nested directories of Dir1.

• copy *.txt *.bak

  For each *.txt file in the current folder, makes a copy ending with bak rather than txt.

COPY [/D] [/V] [/N] [/Y | /-Y] [/Z] [/L] [/A | /B ] source [/A | /B]
     [+ source [/A | /B] [+ ...]] [destination [/A | /B]]

  source       Specifies the file or files to be copied.
  /A           Indicates an ASCII text file.
  /B           Indicates a binary file.
  /D           Allow the destination file to be created decrypted
  destination  Specifies the directory and/or filename for the new file(s).
  /V           Verifies that new files are written correctly.
  /N           Uses short filename, if available, when copying a file with a
               non-8dot3 name.
  /Y           Suppresses prompting to confirm you want to overwrite an
               existing destination file.
  /-Y          Causes prompting to confirm you want to overwrite an
               existing destination file.
  /Z           Copies networked files in restartable mode.
  /L           If the source is a symbolic link, copy the link to the target
               instead of the actual file the source link points to.

The switch /Y may be preset in the COPYCMD environment variable.
This may be overridden with /-Y on the command line.  Default is
to prompt on overwrites unless COPY command is being executed from
within a batch script.

To append files, specify a single file for destination, but multiple files
for source (using wildcards or file1+file2+file3 format).
