Problem in FTP

I read QA Article: QA00000009133 about  Abaqus Technology Brief."An additional file containing the mesh definition for the external water must be downloaded from the Abaqus anonymous FTP site. From a command prompt complete the following steps:

  1. Open the FTP connection by typing ftp ftp.abaqus.com
  2. When prompted for a name, type anonymous
  3. Enter your email address as the password.
  4. Change the directory by typing cd techbriefs
  5. Download the file by typing get outwater_mesh_mod.zip"

I download outwater_mesh_mod.zip from FTP but can't see other propebly zip file for other Abaqus Technology Brief. (like Abaqus Technology Brief TB-10-COS-1:_ High Fidelity Anti-Lock Brake System Simulation Using Abaqus and Dymola)

Are there any problem?
