I don't know if this is what you mean, but I just copied some pdfs over my LAN by holding the stylus down on them until menu popped up, then choose copy (can do several before doing the next step), then going back to Local and choosing a folder (I put mine in downloads), hit Menu or hold stylus on blank area (I think!) and hit paste. Once your files are in Local you can add to Library or open them (I think).
Is this what you wanted??
