Mirror synchronisation attempts to delete files from the 'left'

[panoramica]

After formatting a 4TB backup drive (for MacOS/Journalled), I started a Mirror Synchronization. After scanning the files in my 4TB source drive (on the left), FFS reported that it could not delete some hidden files (whose names begin with ".") from that drive. I quit the application as I don't want to lose any data from my source drive. Tried the process again with the same result. Version 11.23 Donation.
