This wont work because your browser does not have access to your file system.

you can run this from a node.js server

see https://en.wikipedia.org/wiki/JavaScript#Security

Sir, Can you please tell me how to check the file exist in folder using this node.js server. – Karthick Feb 27 '18 at 14:52
var fs = require('fs'); if (fs.existsSync(path)) { // Do something } – Christopher Rivera Feb 27 '18 at 14:53
you will need to create a myScript.js file and then run it as:node myScript.js – Christopher Rivera Feb 27 '18 at 14:54
Sir, please provide full html code for this example. Please Sir! Please Sir! Please Sir! Please Sir! – Karthick Feb 27 '18 at 14:56
its not HTML. you cannot check it using HTML. you need to use a server side language like node. please google node.js and "read file using node.js" – Christopher Rivera Feb 27 '18 at 15:01

You can't access local files in modern web browsers. There is the HTML5 File API, but that involves direct user actions, you can't just use whatever files you please.

There is no way you cant access files using your browser , JavaScript is a view language its interact only with the browser, to be able to access local file you need to use a back end platform such as NodeJs or Php

As I learned years ago you cannot access local file system with JS from browser, but things change. You can find more info here:

Local file access with javascript

The article directs you to MDN but the solution works only in certain browsers:

That API creates a virtual file system that lets the web app read and write its own files there. It still can't access aribtrary files on the user's computer. – JJJ Feb 27 '18 at 15:18
