[/Overwrite:{Yes | No | Append}] Determines whether the file specified                                      in /DestinationImage should be                                      overwritten if an existing file with that                                      name already exists. If yes, the existing                                      file will be overwritten.                                      If no, the process will error if a file                                      with the same name exists.                                      Append indicates that if a WIM file with                                      the same name already exists, the                                      generated image should be appended as a                                      new image within the existing WIM file.                                      The default value is 'No'.
