If an assembly contains unresolved file references, when I try to open it Inventor allows me to try and resolve this with the Resolve Link dialog. But if I choose to skip all for whatever reason, once I've opened the assembly there's no easy way for me to see which sub-assembly/assemblies contain the missing reference. I have to expand folders, patterns, assemblies, etc. until I find the one with the little question mark next to it. I prefer to work with unresolved links in this way sometimes because it just makes more sense working with the model than a bunch of file paths and file names in the Resolve Link dialog. But it's nearly impossible with large assemblies where the unresolved links may be burried deep.
Is there a way to list or somehow see which assemblies contain the unresolved links once I've already opened an assembly?
Your unresolved assembly should still show a question mark at the top level, just right-click and choose resolve file. This will take you back to the same option you skipped at start up.

Why would you not edit your Project File to include all the paths. A properly structured Project FIle and Folders will save you time and in the long run.
