I looked at the file size of a project I completed for mobile platforms in Unity. The file is 1.26 GB, only the Assets file is 44.5 MB, only the library file is 1.21 GB. I want to downsize it by a significant amount. I'm not sure exactly what I can and cannot delete in the Library file, and I don't know if this will work.
What are the things that I should definitely not delete in the Unity/Library file for mobile platforms, what can I delete...?
