I am having Lightroom Classic after working for a short time pop up and say there is not sufficient space. It says it needs 20MB on the C drive. When I check my C drive it has 18GB free. The pop-up will not go away and I need to force close the program. I checked a similar post and it said to clear the trash bin, which did not help. It is popping up when i am doing all sorts of things. One time on a panorama merge, once while using a masking brush. It is using the most up-to-date version. Any help is appreciated.
Yes, it is the C drive. It is under 20% free. I keep all photos on the D until it gets full then I move them over to an external drive. The D has a lot more space and is about 50% free currently. Can I change it to reference the D instead of the C?
