Is there a way to identify/clean un-used assets of my project?

Hello.

I’m trying to make my project lighter, so final shipped package doesn’t weight unnecesary ammount of megabytes just because I added many assets that comes in packs.

Is there a way to quickly and massively identify all non-referenced assets and delete them?
Or at least exclude them from the final package? (this would be even better)

Regards
