c (Copy  ):copy file or directory.
                directory copy dose not copy the directory itself,but
                copy its all member unless /c option specified.
                When wildcard mask is specified at opened dir,
                copy is done using that wildcard.
                enter in new-name column same operand as XCOpy command
                except copy source file name.
                /s (also copy sub-directory) is added as default,
                If target is directory,source file or member of directory
                is copied into the directory.
                If target is wildcard,source file or member of directory
                is copied into the parent directory changing the name.
                by that wild card.
                You must specify /s- to avoid sub-directoty copy.
                To override existing file,specify /y or /r after target
                filename like as XCOpy cmd.
                Without /+ option,File attribute like as timestamp is
                copied.
