Unexpected question mark on file
Finder v13.4 marks files in either list or icon view with a white exclamation point in a red circle.
It appears on every file of every type in my user space (/Macintosh HD/Users/<me>/), both on the disk and in cloud storage, but not files on SMB mounts or attached USB drives.
This just started happening today. What's the cause and how can I get rid of it?
