Copy using FIND REFERENCE

Hi All

I have two different assemblies taken from two different locations. Assemblies having few common parts in it. Now i need to save both assemblies with its part and part drawing in a common folder. While doing find reference or pack and go, second assembly common parts need to be overwritted since the parts are already available when we do find reference of first assembly, my question is wheather the reference of common parts in first assembly will retain or it will break?

thanks in advance
