Where are .dnn files described?

I am curious about this as well. I do not mean to steal the focus of this thread, but I have a question that applies to .dnn files.

I have my .dnn file, and in it I have the following:

<file>
          <path>[app_code]</path>
          <name>EventBase.vb</name>
        </file>
      <file>
          <path>[app_code]\Components</path>
          <name>DataProvider.vb</name>
        </file>
      <file>
          <path>[app_code]\Components</path>
          <name>EventController.vb</name>
        </file>
      <file>
          <path>[app_code]\Components</path>
          <name>EventInfo.vb</name>
        </file>
      <file>
          <path>[app_code]\Components</path>
          <name>EventNotification.vb</name>
        </file>
      <file>
          <path>[app_code]\SqlDataProvider</path>
          <name>SqlDataProvider.vb</name>
        </file>

This gives me a error about the files not being found in the resources.zip. They are there, they are in the root of the zip, and if I remove these lines, the files get moved into the "DesktopModules\MyModule" folder.

I'm curious why they are being reported as not found and / or how I can get them to be moved to the App_Code directory.

Overall though, I would just like more info on the .dnn files.

I apologize for the lack of information, in this case I suggest to get it from the core source code, that is handling the file.
