var path = require('path');
var fs = require('fs');

var dirPath = path.join(__dirname, 'files');

fs.readdir(dirPath, function (err, files) {
    if (err) {
        return console.log('Unable to scan dir ' + err);
    } 
    files.forEach(function (file) {
        // Do something with the file.
        console.log(file);
