Problem renaming/moving folders

"there are sooooo many existing complaints about this"

"The folder xxxxxx could not be renamed or moved."

Searching back four years for that error message with both the forum search and Google search, I found three threads with posts from five people:

Most LR error messages like this one can be issued due to many different causes.  Your particular problem could be completely unrelated to these other five people, or you could be tripping over the same issue as one or more of them.

With so few people reporting the error message in the past four years, Adobe will most likely not pay attention unless they can reproduce the problem on their own computers.

As a next step, I recommend doing the LR menu command Help > System Info and copy/pasting the entire contents here so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set.
