I use these. Shoud work for you as well.

    public async Task SaveFile(string fileName, string data)
    {
        System.IO.IsolatedStorage.IsolatedStorageFile local =
            System.IO.IsolatedStorage.IsolatedStorageFile.GetUserStoreForApplication();

        if (!local.DirectoryExists("MyDirectory"))
            local.CreateDirectory("MyDirectory");

        using (var isoFileStream =
                new System.IO.IsolatedStorage.IsolatedStorageFileStream(
                    string.Format("MyDirectory\\{0}.txt", fileName),
                    System.IO.FileMode.Create, System.IO.FileAccess.ReadWrite, System.IO.FileShare.ReadWrite,
                        local))
        {
            using (var isoFileWriter = new System.IO.StreamWriter(isoFileStream))
            {
                await isoFileWriter.WriteAsync(data);
            }
        }
    }

    public async Task LoadFile(string fileName)
    {
        string data;

        System.IO.IsolatedStorage.IsolatedStorageFile local =
            System.IO.IsolatedStorage.IsolatedStorageFile.GetUserStoreForApplication();

        using (var isoFileStream =
                new System.IO.IsolatedStorage.IsolatedStorageFileStream
                    (string.Format("MyDirectory\\{0}.txt", fileName),
                    System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.Read,
                    local))
        {
            using (var isoFileReader = new System.IO.StreamReader(isoFileStream))
            {
                data = await isoFileReader.ReadToEndAsync();
            }
        }

        return data;
    }
