Parts saved internal to assembly file.

I am a bit frustrated with this feature.

In the past I would always save my new parts to a different fileand it worked fine.

Yesterday I created an assembly with a single defined part, and 6other parts referenced to it.

Today when I was finishing up the design I saved all of those partsinto different files and saved them where the original part andassembly are located. As soon as I did this all of my referencesdisapeared and the dreaded negative signs were everywhere.

Is there something I am doing wrong or are others having the sameproblem?

Thanks
