I have a function in my project that loads files, might help you a bit:

var app = express.createServer(
    express.bodyParser({uploadDir: "public/files", keepExtensions: true})
  , express.cookieParser()
  , express.session({ secret: 'keyboard cat' })
);

app.post('/upload', function (req, res) {
var msg = '';
var img = '';

//console.log("type: "+req.files.image.type);
//console.log("size: "+req.files.image.size);

if(req.files.image.type != 'image/png' && req.files.image.type != 'image/jpeg' && req.files.image.type != 'image/gif')
{
    msg = 'Invalid format, accepts only: jpg, png and gif.
';
}

if(req.files.image.size > 307200) // 300 * 1024
{
    msg += 'File size no accepted. Máx: 300kb.
';
}

if(msg == '')
{
    if(diff > 0)
    {
        name = name.substring(name.length-diff, name.length);
    }

    var date = new Date();
    var name = req.files.image.name;
    var diff = name.length - 20;
    var rnd_number = Math.floor(Math.random()*101);
    var new_name = date.format('yyyymmdd_HHMMssl_') + rnd_number +'_'+ name;

    fs.renameSync(req.files.image.path, 'public/files/img'+new_name);

    img = '';
}

res.render('admin/upload', {layout: false, img: img, msg: msg});

})
