I am using LR5. I have a folder on my server with 2054 files. I am able to access the folder in the Library and Develop modules, even making adjustments to the pictures. However when I try to add more pictures to the folder in the import process, the folder is not listed on the right panel giving me this folder as a destination folder.
Using Explorer/Finder, check the permissions on the folder to make sure you have READ and WRITE access.
Joe, thank you for your idea. All permissions are correct, I checked to make sure. Still not giving the folder for import.
