Would I need to delete unused assets from my Unity packaged build?

I'm going to make a release for my Unity game.

Does Unity include unused assets in build output? Would removing unused assets from a project reduce build size/Time?

I want to know if Unity packages all the assets to my build (which I would need to delete), or if Unity packages only the assets that are actually used in the game.

• not very clear what your asking. could you explain it better? Apr 15 '16 at 10:06

• The one exception to this is assets within a folder named "Resources" — this special folder name tells Unity "I might dynamically load this asset by name, so make sure it's always included even if it's not referenced anywhere" — so make sure you keep only assets you're actually loading via Resources.Load in these special folders. Also, all scripts are always included. They're small, but if you want to shave off everything unused then you should delete scripts you don't need. Apr 15 '16 at 13:45
