When I batch rename selected files in Bridge, it's not renaming some files at the end of the batch. So I'll re-select those ones and try and batch rename them, and it'll do rename a few of them and then leave off some at the end again. It's also changing some JPEG files to CR2 files when I batch rename.
Have you tried resetting your preferences?
Yes, it didn't fix it 😞
What operating system and where are your files stored?
Operating system is MacOS Catalina 10.15.1. My files are stored in various locations and this is happening on both my Macbook and iMac no matter where the files are stores. I've used Bridge with files stored on the computers' desktop and various hard drives, and I'm still having the same problems on both computers with various locations where files are stored.
