Stacking Mod Help ????

Hmm, this I could not tell you …
They are not included in my own Mod Folder …
Were do I find them and should they be in my Mod Folder along with the copies of Blueprints ?

Also when I copy the Blueprints, they seem to lose all Reference links as to which other items are associated with them.
How do I keep all the links in tact ?
