Export or Print existing Bills of Materials

I am using Bill of Materials which I entered thought "Inventory & Service Records" "Build". 

I have entered over 70 manufactured items each of which have Bills of Materials.   Is there a way to import the other 70 bills of materials related to manufactured items?

I would like to confirm what was entered.  I cannot find a way to either printout the bills of materials or export them.  Can I go to the data files and extract them?  If so, what is the file name?

Any assistance will be greatly appreciated.
