is there a way to delete the big RAW File and keep only the processed JPG when finished with work and there is no need to keep the large RAW Files.
Are you using Lightroom CC
As you've mentioned that you'd like to delete the actual raw image after you import your images, . Are you saving your images on cloud and trying to save some space by deleting the raw image?
