Unable to rename folders

Were you able to figure this out? I'm having the same problem. I just downloaded Photoshop and only have renamed 2 folders so far. (Like literally, other than uploading a batch of pictures from vacation, it's the only thing I've done in the program so far.) Upon trying to rename the 3rd folder, I received the same message as you. I can guarantee there isn't another folder with the same name. I'm trying to rename it using the same pattern as the last 2 folders (name of place followed by date, and the date is a different than the other folders), so there isn't any reason for this message to appear and prevent me from renaming the folder. Frustrating.

It's most probably because you already have existing folders with the same name. It's not existing files with the same name in other folders. For newly imported photos, it can't be a read-only file location. If your folder names includ only letters, numbers and spaces it can't be 'invalid' characters either.
