jit.matrix unable to read a jxf located inside a subfolder

One potential ugly workaround for this is to use filepath object but what is not clear if this will work in all situations (e.g. having two subfolders in the same folder with same files--which one will filepath recommend first?). This still leaves lingering questions like, how can one instantiate max objects inside mxj (e.g. a filepath), and if they are instantiated in such a way, will their properties affect the entire patch (including other instances of mxj) or just the mxj instance?
