I've never zip archived them, and have only saved them to Mac formatted hard drives. I can't recall ever using FAT or EXFAT formatting, only used Extended Journaled for years, and now APSF, but it happened before APSF. Its gotten worse since APSF though.Did you ever zip them together with a third-party archiving app? Or copy them over a network? Or save them on a FAT or EXFAT formatted disk?
