I am having a problem with Lightroom CC - I shoot with a Nikon D3 and import raw files (NEF). After editing, when I try to convert them to DNG using the "delete originals after successful conversion" option , It goes through the process
(I can see the progress bar in the top left corner). When complete, I look at the folder, and there are only NEF files listed. No DNG files at all.
Please try to convert raw files from a different folder and check whether you are having same issue.
It can be possible that the other folder you have tried with does not have proper permission to make changes.
Please let us know if it helps.
