# A primer for GridFS using the Mongo DB driver
In the first tutorial we targeted general usage of the database. But Mongo DB is much more than this. One of the additional very useful features is to act as a file storage system. This is accomplish in Mongo by having a file collection and a chunks collection where each document in the chunks collection makes up a **Block** of the file. In this tutorial we will look at how to use the GridFS functionality and what functions are available.

## A simple example
Let's dive straight into a simple example on how to write a file to the grid using the simplified Grid class.

    var mongo = require('mongodb'),
      Server = mongo.Server,
      Db = mongo.Db,
	Grid = mongo.Grid;
