I can describe what I do
To start with, I import from card to Zoom Browser (My Pictures) RAW images
In LR I choose "import" then choose My Pictures and the folder I want to work with. I open that folder, choose the images I want to work in LR and import them to LR. When finished with them I export them as jpgs. to a new folder on my desktop. Then what I have is the RAW images in their original folder and the jpgs. in a new folder. I have done this for years with no problems now suddenly this is whats happening.....
I am doing everything as described above BUT when I choose the images from the original folder in My Pictures, I now get a "copy"?? of the image in LR and it also puts a copy in the original folder (as pre LR, no work done on it) It comes into LR as a copy ....instead of IMG_4061CR2 it shows up in LR as IMG_4061CR2 It never did this before and I suspect that I accidentally somehow changed something I was doing, most likely in the import screen. But I don't know what I've done??
As a result of this I end up with the original "IMG_4061CR2" and a copy "IMG_4061-2 CR2" in my original folder. And I do have the exported jpg. in the new folder.
When I start to import and the import screen shows up it says:
File handling - Copy photos to a new location and add to catalog.
