DocumentDir,
CacheDir,
DCIMDir,
PictureDir,
MusicDir,
DownloadDir,
MovieDir,
RingtoneDir } = rawJsiModule.Dir

RAW synchronous Write

    // Data must be base64 
    writeSync(data:string,path:string):string;

RAW synchronous Read

    readSync(path:string):string;

RAW asynchronous Write

    // Data must be base64 
    writeAsync(
    data:string, 
    path:string,
    callback(error:string,payload:string):void):string;

RAW asynchronous Read

     readAsync(
    path:string,
    callback(error:string,payload:string):void):string;

RAW Concurrent Write

    // Data must be base64 
    writeConcurrent(
    data:string, 
    path:string,
    seekp:number,
    callback(error:string,payload:string):void):string;
