Finding Unreferenced Elements
FMPerception can help you find elements that may not be referenced directly by any other elements. These may be candidates for removal. However, they may be in use through one of the indirect methods of targeting FileMaker elements. It's important to understand that there is a difference between "unreferenced" and "unused". We published an extensive document of this topic on our website. Please check it out.
We also discuss various techniques for ensuring that elements are referenced by something so they don't show up on the unreferenced report

After you open any DDR, you will find unreferenced items in the slow query section. You'll see a section for Unreferenced Fields, Layouts, Custom Functions, Scripts, Value Lists, and Table Occurrences.
