Bridge Downloader puts RAW files in a hidden folder - any ideas?

Bridge CC 2018 btw.

> OK, so I thought that this might be an issue with this particular machine, but now I'm having the same problem on a 32G Windows 10 computer, where the files are stored on an 8TB MyBook. The files are there, but it's annoying to have to move them everytime I download.Interestingly, JPEG files download normally. It's happened with RAW files from Sony, Olympus, Panasonic and Fuji.Any ideas on what might have cuased this? >
Are you saying you work in the Advanced dialog, tell it where to put the files, how to name them, etc., and it just ignores you and sends them to some hidden folder? I'm on a Mac, not Windows, and use Nikon, but I've never heard of this one from anyone. Not recognizing the device, yes, but overriding your destination? That's weird.

If you're designating the destination, it sounds more like some setting in your OS setup than something coming from Bridge, because  raw or JPEG really shouldn't matter. I shoot raw + JPEG without a problem. Really weird is it's taking JPEGs off the card and finding the right drive, but not raw files.
Hopefully someone from the Bridge team will see this (they're sometimes here), or Staff here might call their attention to it.

I don’t understand it at all - I also thought it might be an OS thing, but it happens on Win 7 and Win 10 - I’m specifying the download location using Bridge’s downloader. I also considered that it might be an antivirus bug but I have AVG on the Win 7 machine and (at the moment) only Win 10’s inbuilt security on the other machine. Stumped!

Logged in with a different account there - I’m still the OP

I really hope someone can think what's happening with this. I just have no further ideas, beyond trashing Bridge's prefs and seeing if that fixes things. It's a real pita, but sometimes it makes a difference over the strangest things. Are you on the latest version of Bridge and Camera Raw? If not, what versions? Not that that should be making a difference, but you never know.

I’m on the latest versions of both. Will have to see if I can reset Bridge or perhaps roll it back.
