I have some folders that contain files that are completed, and rather doubtful that I will ever have a need for them again. To be on the safe side, I'd like to have them available just in case, but don't need or want them in my working catalog. What I want to do is archive the catalog and all the image files on a removable drive. I think In this case a USB stick because the largest folder is about 15 GB. I think I can accomplish this by using the "Export Folder as a Catalog", but if I check export negative files, will it transfer the photos from their original location as well or do I still need copy the image files over?
