Assets on iPhone

Ola!

How careful do I have to be when putting assets into the Project area inside Unity? I am sure this will be the same answer for iPhone as Unity standard but I am developing an iPhone game currently.

I am wondering that if I have several versions of a texture or a mesh, in the Project folder BUT they are NOT in the hierarchy area in Unity, when I Build and Run my xCode project do those assets which are not used in the game but are stored in the project folder, get put into my final executable file?

Unity will only include assets that are referenced in the scenes included in your build. This should be the same for iPhone and normal Unity

Thanks.
