I have the same issue.
OM-1 generates BIN files in [CARD_ROOT]/ALBM/ALB97ZZ5.BIN (for me, not sure if the file name differs between camera bodies), and Photo Mechanic ingests this. Not only that, but it appears that the BIN file has date and time set to when the card was last formatted, thus when ingesting and renaming by date, Photo Mechanic creates an additional folder with an old date that I have to then go hunt for. Easy enough to script, but still annoying.
I also have the same problem with Sony A7C mark II - this time the BIN file is named [CARD_ROOT]/PRIVATE/DATABASE/DATABASE.BIN and also appears that its date is when the card was last formatted.
Both BIN files aren't affected by any file rename ingest settings, only their destination folder obeys its settings. Which I guess at least makes it easier to find and delete them after ingest, but it would be lovely if Photo Mechanic could be configured to ignore them somehow.
I'm running Photo Mechanic Plus Version 6.0, build 7102 (796dd4a) on macOS, but I've had this problem ever since I got the program, and I've regularly kept it up to date.
