Ubuntu Multimedia :: MTP Device Folder Management

I own a Creative Zen, and have already successfully used both Rhythmbox and Gnomad to transfer files to it. But the problem is that I can't manage my "files" (not my "songs"). Banshee didn't work, and Exaile is not recognising my Zen (probably I'm missing some libraries or plugins). I've heard Exaile let's me manage the files in my MTP device, is that so?Whenever I transfer any song to my Zen, it is transfered to my /music folder instead of being transfered into an /artist-album or an artist/album folder. It is kind of messy, I want to keep my files organized.

And if I try to move my files manually (from my HD to my device, or within my device) by letting Nautilus automatically mount my Zen as an external device, then it doesn't recognizes the files I've moved.So, is there any workaround for me to manage my files in Zen without making them unrecognizable to it, say, using Rhythmbox? Or is there any other software that allows me to manage my files in such manner?(From what I've googled, it seems that this is a general problem for most of MTP devices, hence the title of the thread.)
