Pack and go file export problem

Hello

We notice that when exporting an assembly using the pack and go tool, far too many files are copied.
The assembly in question has 3 parts, in the end I end up with 40 parts in the reception file.

Have you ever encountered this problem? Is there a particular adjustment to be made?

Thank you for your help,

Kind regards

Do you have any external references in this assembly?

Hello

It's true that the options of Pack&Go are not immediately obvious:
Step 1: (Top Left-Check/Uncheck as needed))

otherwise by double clicking on the column headers:
You can add or remove selections according to criteria (names, locations, etc.)

On the other hand, you should avoid external references (as @sbadenis says), normally they are restored with the new project (the copy) unless they are in error or sometimes just broken, and this may create references with the original...
