Is there any way to hide the .BridgeCache files in CC?

I'm new to CC, but the way I understand it is that I can copy files to my CC folder and send the client a link for them to proof. The only problem is that I'm seeing .BridgeCacheT and .BridgeCache files in the cloud. I know what these files are and what they're for, so I don't want to delete them. But it seems confusing for them to be viewable online, and the client certainly doesn't need to see them.
