I am trying to develop an Eclipse Plug-In and the documentation says to
extend the org.eclipse.ui.dialogs.WizardNewFileCreationPage class.
However, this class does not exist.
I downloaded the Eclipse for RCP/Plug-In Developers version 3.3.2. I have
also checked in the another location that was suggested in previous
newsgroup listings - org.eclipse.ui.ide.WizardNewFileCreationPage. This
file does not exist in either of these locations.
Any idea where I can find it?

There are some important fundamental concepts that you need to get a
handle on.
First, the build path is used only for building. In a plain old Java
project, the build path is also used as the runtime classpath (assuming
you don't override it). As a general rule, you should almost never need
to change the Java Build path when you're building plug-ins.
In the Eclipse runtime (Equinox), you have to explicitly specify
dependencies between plug-ins (also known as "bundles"). So, if you want
to use the WizardNewFileCreationPage in your plug-in, you have to have
the plug-in that defines WizardNewFileCreationPage as one of your
plug-ins dependencies.
To set this up, double-click on either the manifest.mf or plugin.xml
file for your plug-in and navigate to the "Dependencies" page. In the
"Required Plug-ins" area, click "Add" and add the plug-in that defines
WizardNewFileCreationPage (org.eclipse.ui.ide).
You should then be able to access it from classes in your plug-in.
I recommend that you find a decent tutorial on plug-in basics before you
try to get too far...
Try this one:
