To move one or more files:
MOVE [/Y | /-Y] [drive:][path]filename1[,...] destination
To rename a directory:
MOVE [/Y | /-Y] [drive:][path]dirname1 dirname2
  [drive:][path]filename1 Specifies the location and name of the file
                          or files you want to move.
  destination             Specifies the new location of the file. Destination
                          can consist of a drive letter and colon, a
                          directory name, or a combination. If you are moving
                          only one file, you can also include a filename if
                          you want to rename the file when you move it.
  [drive:][path]dirname1  Specifies the directory you want to rename.
  dirname2                Specifies the new name of the directory.
  /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.
The switch /Y may be present in the COPYCMD environment variable.
This may be overridden with /-Y on the command line.  Default is
to prompt on overwrites unless MOVE command is being executed from
within a batch script.

Deletes one or more files.

DEL [/P] [/F] [/S] [/Q] [/A[[:]attributes]] names
ERASE [/P] [/F] [/S] [/Q] [/A[[:]attributes]] names

  names         Specifies a list of one or more files or directories.
                Wildcards may be used to delete multiple files. If a
                directory is specified, all files within the directory
                will be deleted.

  /P            Prompts for confirmation before deleting each file.
  /F            Force deleting of read-only files.
  /S            Delete specified files from all subdirectories.
  /Q            Quiet mode, do not ask if ok to delete on global wildcard
  /A            Selects files to delete based on attributes
  attributes    R  Read-only files            S  System files
                H  Hidden files               A  Files ready for archiving
                -  Prefix meaning not

If Command Extensions are enabled DEL and ERASE change as follows:

The display semantics of the /S switch are reversed in that it shows
you only the files that are deleted, not the ones it could not find.
