I think he wanted to know what settings he should use when saving an item to include the shaders and make it a sort of self contained files which do not rely on external support files like texture map images etc, or includes the texture maps directly in the saved file, making the scene portable.  I believe you simply save the object and save the maps internally when it prompts you.  Also, if you want to save the object to use in your object browser, just save it to the correct folder.  I usually use C:Program FilesDAZCarrara 6PresetsObjectsMy Objects.   And save it with the scene preview so you get the little icon in your object browser.
