Is there an easy way to see all the photos that need to be "reconnected"?

Is there any easy way to see all the photos that have become unconnected in the Catalog and need to be reconnected with the file?

File > Reconnect > All Missing.

Thanks. Does that allow me to see all of them or just open up that dialog that looks for each one one by one?

It will give a complete list (albeit in a small, scrollable window). You can then delete them from the catalog or reconnect them individually, by folder, or all at once.
