General Build Settings

Support I have 10 prefabs, 10 textures, 5 materials in my assets folder.
I have 1 scene. But Only 5 prefabs, 5 textures, 2 materials are used in that scene.

Now if I try to build this scene will it build all the contents from Assets or only the the one used in that scene.

I am new to Unity. Using Unity 5 version.

Can anyone answer this basic question please.

Thanks in advance.

Unity strips most unused Assets during
the build, so you don’t gain anything
by manually removing Assets from the
Project. The only Assets that are not
removed are scripts (which are
generally very small anyway) and
Assets in the Resources folder
(because Unity can’t determine which
of these are needed and which are
not). With this in mind, you should
make sure that the only Assets in the
Resources folder are the ones you need
for the game.
