F.A.Q's

Here you will find answers to the most frequently asked
Teacher's Resource CD-ROM questions.

What is DRM?

DRM stands for Digital Rights Management. It is a form of electronic security implemented on some contents of the Teacher's Resource CD-ROM. This has been done in order to protect our copyright on products sold electronically.

How does the DRM system work?

Our DRM system works by (1) installing the FileOpen plugin, (2) creating a BIOZONE DRM account using a products serial number and (3) using that account to authenticate to our server when opening a protected file.

What is a protected file?

A protected file is a file which DRM has been applied. Most commonly these files include - but are not limited to:

• Workbook files
• Model answer files
• Additional activities files

What does the FileOpen PDF Plug-in do?

This plug-in is required to open PDF files encrypted by FileOpen rights management software, and is authorized by Adobe Systems to load in Adobe Acrobat and the free Adobe Reader. The plug-in manages the open and print commands in the Adobe Reader according to the access controls set by the publisher. Any access controls on the encrypted files have been placed there at the discretion of the document publisher. The plug-in alone will not grant access to encrypted files; you must follow the publishers' instructions for obtaining access.

Where does the FileOpen software get installed?

Adobe Acrobat loads plug-ins at application startup from a pre-defined directory, so the FileOpen.api plug-in has to be copied to that directory. By default, on Windows, the directory is:

C:\ProgramFiles\Adobe\Acrobat|Reader\plug_ins

On Macintosh the plug-in is difficult to find, as it becomes part of the "packaged" Acrobat/Reader application, but you can find a link to it by selecting the launch icon for the Adobe viewer and clicking Apple+I then finding the drop down for Plug-ins. From here you should FileOpen.acroplugin. You can also add/delete the plug-in from this menu.

Locations on Linux may be obtained by searching for "FileOpen".

Which privileges are required for the install?

Typically, Windows users must have PowerUser (or Administrator) privileges to run the installer, though all that is really required is write-permission to the Acrobat plug-ins folder.

Which operating systems are supported?

The FileOpen Client will work on Windows 98 or later, Macintosh OSX and Linux.

How do I remove the FileOpen software?
