Isolated Storage in Windows Phone 8 or 8.1

Question

Hello,

I am implementing the Isolated Storage in my Windows Phone Application, by below code,

 

IsolatedStorageFile fileStorage = IsolatedStorageFile.GetUserStoreForApplication();
StreamWriter Writer = new StreamWriter(new IsolatedStorageFileStream("TestFile.txt", FileMode.OpenOrCreate, fileStorage));

In which we create the txt file to store data offline, right?
I have doubt that, When this code will run, somewhere in our Windows Phone Device the data will save, means this txt file save? I want to know the exact location path where the data will be saved in the Device memory, which is stored from app via Isolated Storage ?

What will be path exact location in device memory, where this Isolated Storage will save the data from app? And is End User can access this data which is store by isolated Storage in Windows Phone Device memory?
