Thanks for the quick reply. I'll look into that other way. Just was hoping for a seamless start on the new machine. In the mean time any idea what would cause the file to be missing or how I can correct this. I just did a straight export from my old machine and directly import to the new one.

The only things I can think might cause issue are as follows.

1. I just upgraded from version 4. whatever to the latest version but I did that on the old machine before the export and everything seems to be working well on the old machine. No problems adding books or drm issues.

2. Because of the size of the files I had to upload them to google drive then download them to the new machine. I don't have a portable drive big enough to straight transfer. And to download it had to zip them.
