Question

I am trying to write some text file into isolated storage in WP7 through silverlight code. I want to somehow retrieve the file later and save onto PC. How do I see and get it? Is there some kind of file explorer? Where does it really saved to?

        using (var store = IsolatedStorageFile.GetUserStoreForApplication())
        {
            store.CreateDirectory("MyOutput");

            using (var stream = new IsolatedStorageFileStream("MyOutput\\data.txt",
                                                  FileMode.OpenOrCreate,
                                                  FileAccess.Write,
                                                  store))

Another option is to use the Isolated Storage Explorer Tool (ISETool.exe) which comes with the 7.1 SDK. It’s a command line driven tool available in C:\Program Files\Microsoft SDKs\Windows Phone\v7.1\Tools\IsolatedStorageExplorerTool\ (C:\Program Files (x86)\Microsoft SDKs\Windows Phone\v7.1\Tools\IsolatedStorageExplorerTool on a 64 bit machine). To interact with your application’s Isolated Storage you need to specify if it should connect to a physical device or the emulator as well as the product ID (The GUID specified in your WMAppManifest.xml file). Eg. To download all the files from your emulator to C:\Foo\ you’d use;

ISETool.exe ts xd {ProductID Here} C:\Foo

Run ISETool without arguments to get help on its exact usage. ts here stands for “Take Snapshot”, other options are rs (Restore Snapshot) and dir (list contents). xd is “Emulator” and de is “Device”.

Once you’ve ran this you can navigate to C:\Foo and see the exact contents of the Isolated Storage for your application.

It takes a bit more fiddling than the wp7explorer tool but doesn’t require you to link to an assembly or make any code modifications.
