We upgraded from LR2 to LR3.6 and somehow lost one folder in the process. We were able to get all other folders and their XMP files, but had to re-import the one folder's RAW images but all XMP sidecars for only that one folder are missing. Is there a way to restore that one folder without restoring the entire catalog? To complicate issues, the re-importation of that one folder resulted in many images being loaded that we had already deleted. Therefore, the last catalog backup does not have the same number of photos in that file as we re-imported. Any thoughts?
