Here, the File object must use an absolute path, "C: \". In addition, the directory separator cannot use "\", and must use "\\'.
Tip: The Terminator of a text file line is ('\ n') or (' \ R'), but the browser does not recognize the terminator of these lines. Therefore, to display a line break in the browser, you must add an HTML Tag after each line. <br>
