> Cannot create folder into cordova.file.externalRootDirectory on Android 6.x Marshmallow. It always returns encording error (12), while on Android 5.x (Lollipop) the same code works fine.
> On Marshmallow devices I can succesfully create folders only into cordova.file.externalDataDirectory.
> No matter the value of preference AndroidPersistentFileLocation or AndroidExtraFilesystems.
> Code (some ES6, sorry)
> This snippet uses WinJS Promises - should work with native promises as well or you can just remove promises and pass succes and fail callbacks. It should create MY_Folder/test (both folders, like mkdirp) in the SD Card (regardless if emulated or not) root directory. It works fine with 5.x devices, but returns always FileError.ENCODING_ERR on Marshmallow.

> }
> {code}
> I suspect it has something to do with the way the storage should be handled on Marshmallow, see for instance http://developer.android.com/guide/topics/data/data-storage.html and https://source.android.com/devices/storage/
