title: Multer create new folder with data
body: <p>I use <a href="https://github.com/expressjs/multer" rel="noreferrer">multer</a>.</p>
  <h3>Question 1</h3>
  <p>When I put the following snippet in the <code>app.js</code></p>
  <pre><code>app.use(multer({
          dest: './uploads'
      }
  ).single('file'));
  </code></pre>
  <p>it creates a new folder under the root folder, my question is about this new folder's lifeCycle, When it'll be deleted? How much the size of the folder could be after 100 call?</p>
  <h3>Question 2</h3>
  <p>If I don't want to limit the file size, what I should put in the configuration?</p>
  <pre><code>app.use(multer({
      dest: './public/profile/img/',
      limits: {
          fieldNameSize: 50,
          files: 1,
          fields: 5,
          fileSize: 1024 * 1024
      },
  </code></pre>
  <p><strong>Update</strong></p>
  <p>My app is built like</p>
  <p>app.js file contain</p>
  <pre><code>    app.use(multer({
              dest: './uploads'
          }
      ).single('file'));
  
  app.use('/', routes, function (req, res, next) {
      next();
  });
  </code></pre>
  <p>The route file look like following</p>
  <pre><code>appRouter
      .post('*', function (req, res) {
          handler.dispatch(req, res)
      })
      .get('*', function (req, res) {
          handler.dispatch(req, res)
      })
  </code></pre>
  <p>And in third file I use the unzip like following</p>
  <pre><code>update: function (req, res) {
    var filePath = path.join(req.file.destination, req.file.filename);
              var unzipper = new Unzipper(filePath);
              unzipper.on(&quot;extract&quot;, function () {
                  console.log(&quot;Finished extracting&quot;);
                  res.sendStatus(200);
              });
              unzipper.on('progress', function (fileIndex, fileCount) {
                  console.log('Extracted file ' + (fileIndex + 1) + ' of ' + fileCount);
              });
              unzipper.on('list', function (files) {
                  console.log('The archive contains:');
                  console.log(files);
              });
  
              unzipper.on('error', function (err) {
                  console.log('Caught an error', err);
              });
  
              unzipper.extract({
                  path: &quot;./&quot;
              });
          }
  </code></pre>
