Hi,
If you’re moving or relocating folders in Lightroom and you want to keep all of your previous work and settings on it, the trick is that you need to use the “Update Folder Location” option.
Right-click on the folder that your images were previous in, and select “Update Folder Location.” Then select the new folder location.
This will bring over all the previous edits you’ve made, including the metadata that enables Negative Lab Pro to continue editing your negatives from where you last left off.
Hope that helps!
