          • Get the file name into temporary file name.
          • Get the path into the temporary path.
          • Call the method “copy()”.
          • Call the method “deepZipView()”.
        • Otherwise,
        • • Print the first “10” lines of the regular file.
          • Get the lines of files.
          • Create a list.
          • Create a loop,
