How to read resources outside Assets folder

Unity Engine
1

English is not my mother language so my exposition may not be so good, forgive me in advance.

I want to achieve such a function:Package assets outside Assets folder, when the project is running , it can read any resources from the package when it needs.

What should i do?

Thank you in advance.

You can read any assets (e.g images, sound, video, text file) from outside assets folder with the use of Application.datapath and www class.
