Oh about the RSR's: After installing Pro-Pack I went through and deleted the RSR's from my geometries folder as those are no longer used. Gave me about 35% of my drive space back. The RSR's in the libraries folder were a different story. I went into each of my libraries so that pro-pack will do the conversion and then deleted those RSR's. The savings in space was very small. So I would say don't worry about this one as if you miss a file to convert you lose out but not deleting doesn't save much on disk space. My next task is running through all my CR2 files and finding the references to BUM files. These files are fairly large and Pro-Pack has no need for them as it can bring in JPG files as bump maps now. I expect another large increase in my available drive space.
