My LR catalogue has become too large, can I divide it up into 5 new catalogues? what is the best way to accomplish this? Peter
Select the files that you want to move to the first new catalogue, and then choose File / Export as Catalog
. Name it, and where it will go, as well as how to handle the files.
When it's done hen deselect the first selection and do the same thing again each time.
Don't forget to make back-ups. Drives are cheap, lost files are painful.
