Find links coming into a topic

Hi There,

I am using Robohelp 2019 Classic view. I have a topic that is getting too long "Device Maintenance Settings". I created a book and named it "Device Maintenance Settings" I then created topics under this book for each section of the orginal "Device Maintenance Settings" topic. I copied each section over to its new topic page. My next step would be to delete the original "Device Maintenance Settings topic.

I don't know how this will effect my links going out and coming into each new section topic that I created. How can I see which parts of my large Help file are linked into these sections. I'm looking at the  Link View and it shows blue and couple of red lines (broken links I assume). but it's hard to tell if the links are coming in or going out. I checked the book marks but I don't know how to tell what is linking to those.

Bottom line: I need to see if the links coming into my new topics will still link even though they've been moved.

Thanks for your help in advance.
