After finding the folder with most of my pictures on a thunderbolt external volume was moved from directly on that volume to a lower level directory by some magic, I cannot copy the directory back to the volume level. When I try and drag it to the volume, it won't transfer. I can transfer it in finder but not in lightroom classic. The drive is 500Gb and has 32Gb left. The directory I am moving has 433Gb. It is on the same volume. Whatever force or command moved it from volume to lower directory was able to do it with these space limitations. So I thinking it's not space limitations that are keeping me from moving it back. Any help would be very appreciated.
In the Folders panel, right-click one of the top folders in the volume and do Show Parent Folder. Repeat this until you see the folder "/" at the top level. Now you can drag-and-drop a folder onto "/".
