When running LR cc my catalog is in excess of 260k pictures. I started to get a warning that my 500gb SSD C: drive is down to 34gb free. Running Winderstat it tells me my byte count is 175gb. Is there any way to Compress this File or is it based upon the number of Pictures I have in my catalog? Can I move this LR6 Catalog Previews.LRDATA file to a Larger system?
