Re-opening re-named/moved files with internally save parts

Hi,

Ever since I upgraded from SW 2012 to SW 2013 I have been havign a problem opening assemblies with internally saved parts. When I try to open an assembly that I have either re-named, moved, copied, etc that has an internally saved parts, it says the internally saved parts can't be found and have to go looking for them. I basically lose that internally saved part because I don't have it saved anywhere else to go looking for it. In SW 2012 I've never had that problem. Anyone else experience this or is there something that I am doing wrong or must do differently now that I am using 2013, etc? Any help on this would be appreciated. Thanks
