Import a serie of 3ds animation files!

Hi

I want to import an animation to Unity. I can export to for instance 3ds or obj etc., but not fbx! The guides I can find talks about fbx, that is very nice, but with like 3ds/obj I end up with one file for each frame. So 30 frames give me 30 files. I can insert one of them with no problem, but how do I tell Unity to put these together, that is make an animation out of it?

I use Poser. Well I can export to Collada, that gives me one file to work with in Unity.

The point is I would still like to know, whether it is possible (primary in Unity) to merge files into one single animation file!?
