File saving with assembelies

Hello,

I've been working on an assemblie, taking out parts and putting parts in and I was curious if there was a way to save the assembelie and ONLY the parts that are in it, into a fresh directory? I need to zip the project up and send it to someone and have a bunch of extra solidmodels in the same file that aren't being used anymore. Appreciated.
