Where scheme is saved ??

Hi ! ^^

I heard Scheme is not included in project file...

so i heard we need to save out to other folder to share scheme with other developers in a same project...

my queustions are

1. Where scheme is saved ?? (Especially, I want to share pre-action script.. When I zipped project and give other person, script is gone.. no script remand in a project)

2. How to save out scheme so that we can share a scheme file ?

thanks ~~~
