All the edits stay within the catalog.
Have you deleted those files from catalog or from the main folder ?
Have you created any back up of the catalog ?
Thank you for your prompt response. I was running out of internal hard drive space so I deleted from my C drive the folders in my C drive that contained DNG's that LR sent there. I do have catalog backups also in my photo library but when I click on them it opens up LR and still it has the i in the upper right corner and says no file can be found. I think the problem is where LR is looking to. I need to change the path but do I link upto catalog or original raw files or already edited jpegs. Thanks again..
I really don't want to lose my edit history in case I need to go back and re-edit. Many of the edits are no big deal and can easily be reproduced but some are many steps and not easily reproducible.
You just need to tell LR where the images are now located.
Open the old catalog with all the edits.
If you want the external drive to be the new main location of the images, go to the LR Library module, Folders panel on the left.
Select a folder, right-click, "show parent". Repeat as needed until your LR tree looks like the tree shown by the OS.
Select a top-most folder that you are missing, right-click, "relocate" or "find missing", navigate to the external drive's location. Repeat as needed.
Thank you Maniac Joe. I deleted the original linked files on my internal hard drive which were dng files but had copies of the unedited raw files and the exported edited (as jpegs) raw files. I did not have copies of the dng files. So what I ended up having to do was reimport the original raw files which then made a dng copy to my internal hard drive. The link was unchanged but now the files were back in the original pathway so the missing photo alerts disappeared and I was able to see my edit history again. The process was tedious but without the dng files I had nothing to link to anymore so at least the importing again recreated the dng's. I'm not sure if there was an easier way but it seemed the problem was dealing with the deletion not the link. I've been using LR for a number of years but this was a rookie mistake, precipitated by my hard drive being so jammed up that I ended up deleting what I shouldn't have. I should have just moved the dng's and the link to an external hard drive. Thanks again.
Thank you, Jitendra. Please see my response to Maniac Joe. Your link to finding missing photos is a good one. The deletion was the problem though but the tedious reimporting of 15,000 large files at least reversed that. Thanks again.
Read it, finally its sorted.
