I was in the process of importing some real estate photos into LR today when the pop-up said my C drive was full. This has happened in the past, but couldn't remember what to do. So I looked here, Googled it, and found a great YouTube video that shows how to move your catalog to a different drive and how to connect LR to it once this is done.
I moved said catalog to my D drive (I have dual drives). When I am in LR, I click on Edit, it shows the lrcat in my D drive in a folder. When I started to import the images again, the pop-up came up again and said the drive I was importing to (C) is full.
Please tell me how to get these images to import to the D drive so I can get them on my laptop and edit. I have a deadline, of course, which is in a few hours.
Understand that your images are not "in" the catalog. The images are in folders on your computer hard drive. It sounds like you need to do some computer management and move some images off of your hard drive to a different one.
All my images, from raw to edited, are on external hard drives. I literally have nothing on my C drive, except LR / PS. I don't do much in PS.
