I transfered all my data from my old computer to the new one and when I when to edit images in Lightroom all the images have a ? mark. when I locate a image to confirm the location the image is deleted? What do I do to get all the images to be useable?
The Question mark '?' on the folder shows that the folders are missing from the original location.
You need to relocate the missing folders.
If you are still facing issues, please click on the below link to move Lightroom files from one computer to another.
Let me know if this helps.
