Batch Export Option

I have a gun with lots of small parts that I want to export to zbrush as separate OBJ files. In Max there is a very useful addon that lets me do this but I can't for the life of me find a similar addon for Blender.

I think this is such a basic thing that it shouldn't require an addon. So, why not let us export objects as separate files in selected folders, in the format we want? I'm gonna go crazy if I have to individually export each object.
