Renaming files in LR classic does not work. Any file name I type in to use as a replacement returns an error stating I cannot use a dot (.) to begin a filename. I am not typing in a dot. But on the example in the replace window, I see the dot has been put in by the software.
Actually, it completely changed the dialog box, which does not give me the example file name at all, but which also does not put a dot at the start of the file name. I have no idea what just happened, but at least it works. How quirky! Thanks.
