How to delete links that are not used
I always thought that "Package for print" only copied links that are used in the documents, but having done it a couple of times with my current book, I find that many unused illustrations are being copied.
How can I get rid of unused links. When looking at the links folder, there is no way to determine which one are used in the document and which ones are obsolete, so manually deleting them is not a realistic option. Anything I can try?
