Following several online tutorials, I successfully moved most of my Lightroom photos from one external drive which was nearly full to a new 1 TB drive. However, 95 photos out of over 16,000 would not move. I figured out it was because I had originally copied them to the old drive from a CD and the permissions were read only. So I went into Finder-Get Info and changed the permissions on all 95 files to read and write. Now, however, Lightroom will not transfer the folders containing the files to the new drive. It says "A Folder Named . . . already exists at this location." However, the folder doesn't show up in Lightroom. Lightroom did create the folder, and it shows in Finder, but it does not show in the LR catalog and I can't import files into it. What now?
Thanks in advance for any assistance.
Check in Finder if the folder exists in this location. Then - still in Finder - check if it contains any photos.
a) If it doesn't contain photos, delete it and try to move the folder in Lr again;
b) if it contains some photos that don't show in Lr, import the photos in Lr. This will display the folder in Lr. Then in Lr move the photos (not the folder!) from the old location to the new one.
Thanks for the suggestion. I tried this. The folders do exist in the new location, but they are empty. I deleted the empty folders in Finder, then went back to LR 4 and tried to import the folders into the new drive. This time LR gave me an "Unknown error" message, which is terminally unhelpful. Same thing ("Unknown error") when I tried to just grab the images and import them into a folder on the new drive.
Don't import a folder that's already in Lr.
Importing should be used only for images that have never been imported.
Just move the folder in Lr. That means you drag-and-drop the folder in the folders panel.
