Multiple SU files linked

Hi I am new to D5 rendering, so excuse me for the question. I have been working on a scene in Sketch-Up which I have saved with progressive numbers (scene1, scene2, scene3, etc…). As a result I have a D5 file linked to 4 different SU files: how do I clean this mess and only have a D5 file linked to a single SU file keeping all the materials, lights, objects and cameras?

Thanks :pray:t3:

I have managed to solve the problem: I have put all the files I don’t need in a folder and was able to delete it. I could not delete the single files one at a time though.
