From what I have gathered, there is a confusion about this news. Just like what Erel has mentioned, only one folder will be allowed in the external SD card and that is for every application. This is just kinda imposing some discipline in the file system usage. If one needs more folder for his/her external files then it has to be created inside that lone folder or the default storage ( the device flash storage). Another info that I have heard is that ownership is implemented in this scheme hence, from KitKat and future Android releases, there will be no sharing of folders among applications. I just thought , could it mean that if your application wrote some audio files in its external folder then other apps like third party media player would not be able to play those files? No wonder it is not a welcome idea to millions of Android fans. But again, this is only for external SD card.
