Copy an entire folder from streamingAssets to persistentData (Android + iOS)

Hello Everyone,

Can somebody knows how to simply copy an entire folder present in the streamingAssets to the persistentData folder.

In my project it works on iOS but not on Android. I understand the WWW class for the files but not for folder.

My goal :

void copyEntireDirectoy(string src, string dst)

with src = System.IO.Path.Combine(Application.streamingAssetsPath,"levelData") and dst = System.IO.Path.Combine(Application.persistentDataPath,"levelData")

levelData is a folder with multiples subfolders

Sorry for my bad english ...

Thanks !
