Increase Dropbox Space for Free (Windows)

This guide teaches you to increase your Dropbox's space via the referral trick under Windows.

The Trick:

This technique use the following facts:

  1. Dropbox allows you to refer your friends via a URL.
  2. When your friend register using that URL, installed Dropbox client and login, you the referrer’s account will get spaced increase (500 MB at the time of writing)
  3. However, if you think you can get space gain by doing Step 2 on the same computer, Dropbox will consider the referral is not eligible.Dropbox Ineligible Referral

We use the following method to bypass Dropbox’s checking

  • We setup a “virtual machine” (virtual PC) on your main PC. A virtual machine acts like an operating system (e.g. Microsoft Windows) running inside an operating system.
  • We use a MAC address changer software to change the network adapter’s address to fool Dropbox that we are not doing the whole thing on the same PC.

Major Steps:

  1. Install VirtualBox
  2. Install the Dropbox virtual machine appliance either by making it by yourself, or download from me.
  3. Create dummy Dropbox accounts and login.

Install VirtualBox

  1. Download the VirtualBox installer for Windows at here.
  2. Install VirtualBox. You may need to click “Yes” several times during installation.
  3. When complete, you can find the item “Oracle VM VirtualBox” in your Start menu.
