OK, what you need to do is drag the files from a Windows explorer window and drop them right onto the project in the Workbench Project Navigator view.
They will then become part of your project and will be compiled and linked with it.
Make sure to drop the files on the top of the project -- not somewhere in the middle. The best thing to do is collapse the project so you can't see any of what's inside. That way, you can't miss with dragging and dropping.

Here's a snippet from the Eclipse documentation (which should be avaliable to you by using Help->Help Contents in Workbench)

Importing files

Files can be imported into the Workbench either by :

* dragging and dropping from the file system, or
* copying and pasting from the file system, or
* Using the Import wizard.

Using drag and drop or copy/paste to import files relies on operating system support that is not necessarily available on all platforms. If the platform you are using does not have this support, you can always use the Import wizard.
