If I read your question right, you want to view all the VIs referenced in a project so you can ensure you copy all the necessary ones before you try to build?
In that case, open the VI Hierarchy, which will display which VIs are called by which other VIs (
link). Go to View-> VI Hierarchy to view it.
Also, the Run arrow will show as broken when you're missing VIs, so you could just click on it and use the
debugging tools to see which VIs are missing and then go get them.
