I'd like to share my unity project with some friends. Unfortunately, the project folder is large and I'm not sure about what files are generated automatically and can be safety deleted.
What files/folders can I delete and after that, if I zip the project folder and share it with my friends, they can use it?
The root Assets folder and ProjectSettings folder are needed.
Just compress them and send to your friend. They should use the same version of Unity3D as yours for compatibility.
