I want to be able to export all files in the File Library when exporting, even if the file is not linked on any particular content item.

I have been able to hook into the DataExporter.Exporting event but I can't find how to include Global Files as a source.

Can anyone point me in the correct direction?

Here is what i have so far (obviously not working code)

    [InitializableModule]
    public class GlobalFilesExporter : IInitializableModule {
        public void Initialize(InitializationEngine context) {
            DataExporter.Exporting += Instance_Exporting;
        }

        #region IInitializableModule Members

        public void Preload(string[] parameters) {
        }

        public void Uninitialize(InitializationEngine context) {
            DataExporter.Exporting -= Instance_Exporting;
        }

        #endregion

        public static void Instance_Exporting(object sender, EventArgs e) {
            var dataExporter = sender as DataExporter;
            //dataExporter.SourceRoots.Add(new ExportSource(ContentReference.GlobalBlockFolder, ExportSource.RecursiveLevelInfinity));
            dataExporter.SourceRoots.Add(new ExportSource("GlobalFiles???"));
        }


    }
