Mantaining reference links after changing component file paths.

I've created several parts and gave them generic file names.  I then used those parts in several assemblies and subassemblies.  At this point, if I rename the part file in Windows or if I moved them to a different folder, I'll have to individually re-establish the file path link in all the assemblies and subassemblies.  Is there an easier, non-tedious way to do this in 2009 SP4.1?

Thanks!
