I store my "L4 catalog folder " on an external drive. It shows up with 3 folders called: Backups, CacheDocuments, and PreviewCache. For security I copied all 4 of these folders to another external drive using a program called Synccopy.
--Do I need to copy all 4 of these to ensure I have an extra catalog in case of drive failure? Also, when I transfer Luminar to another computer do I use all 4 of these or just the main one?
--As the files flashed by when copying I noticed many of them end in .jpg. I only shoot in raw, could something be changing my pics to .jpg?
Thanks for explaining, I do not want to loose all my editing effort!
