Hm, my 'old' install doesn't have any of the [type][number].rpa files, as far as I can see. Nor are they there when I do a fresh install. Any idea why this might be?
I moved the audio, images, and imov folders (and all their contents) from the last version into the game folder of the new patch. So far so good I am currently playing Chapter 7. Hope that helps.
I've just kinda copy/pasted everything from the 0.7 update into the 'main' folder and overwritten the doubles, and so far it all seems to work. So I guess I'll see.
