Sharing Storyline Projects for Colaboration

Hi All,

This maybe a daft question, but a lot of the queries seem to be 7+ years old.

Is a .Story file sufficient for a developer to pick up a project and continue working on it? while maintaining all the original settings? Such as Project sizing, fonts, player style, colour scheme etc.

Or is there a specific process to follow to fully back up a storyline project and its associated settings? 

We have created a large repository of material developed so far and somebody asked the above. As it is entirely likely that a different developer would pick up a project for update. My honest answer was I didn't know :)
