all my external drives are formatted exfat
my windows pc is NTFS
However I do all the export process on my windows pc.
In detail when I rip a cd or download an album, I export it to a folder that is already on my windows pc (NTFS). I connect the external drive (exfat) to my windows pc, then move the files to the external HDD. When I connect the external drive to my macmini core certain files are not seen by mac.
However if I perform all this on a macos computer there is no problem.
And the files I have sent you one of them is renamed by roon running on macos and the other one on a windows pc
