Thank you for the input. One problem I have not solved is that I use both Lightroom and C1 as presently I only use C1 for my Sony, because it's RAW conversion is much more pleasant to me. I will work on a better folder structure that should allow me to use either engine without problems. I am really considering totally migrating to C1 completely as I am not at all a fan of the lease situation Adobe moved to. It is likely no more expensive than buying updates used to be but it is irksome to me.
