Files Opening with Content from Another File

Hi All,

So I have a part, lets call it Part1. Every time I open certain solidworks parts, it instead opens Part1. When I insert these other parts into an assembly, Solidworks inserts Part1. The file previews in Windows are of the correct parts that I want to insert. Also, Part1 is quite large, and the file sizes of the parts are reflective of their true content (smaller). How can these files be referenced to Part1, and how can I force solidworks to open the correct part. I even moved teh fiel for Part1, and it still appears.

Cheers,

Murray
