I follow a similar pattern but I currently don’t have it in my google drive.
_Assets — Things provided by stakeholders and clients for the design process.
_Process — v1,v2, etc.
_Proofs — before and after pages, and other screenshots from iterations
_exports — actual hand-offs to the clients or stakeholders
I am curious how you handle naming the main project folder if there are several version of that. Like Android Things V3, V4, Etc.
