Something else that's very odd is that when I tried to use FreeFileSync of the RealTracks folder if declined with some kind of permissions error, which I couldn't resolve of the folders in question, nor could I access the contents of the fiolders. After a fair bit of messing about I ended up opening the Properties for RealTracks->Security; set the security for RealTracks sensibly, then Advanced->Change Permissions, checked the "Replace all child object permissions..." and did [Apply]. I can now read the folders and FreeFileSync works on them. I'd earlier done a copy on 2022 and 2023 stuff to this folder, so I don't understand why I apparently couldn't any longer.

I also had the following, which I shall resolve by forcing the distribution copies to overwrite my local copies.
