Answer 1

Isolated storage used in WP silverlight . If you want a temporary folder to store you can use ApplicationData.Current.TemporaryFolder If you want a Folder to store application data for a long time and you need them you can use ApplicationData.Current.LocalFolder If you want your app to have a sync between devices , it means you want to have same data on different devices you have to use RoamingFolder instead of LocalFolder . RoamingFolder share application data between devices and help you to make a more universal app .

Use the ApplicationData class to get a StorageFolder instance for the temp folder:

var tempFolder = ApplicationData.Current.TemporaryFolder;

You can then use the StorageFolder to create a file in the temp folder:

var tempFile = await tempFolder.CreateFileAsync("TempFileName.tmp", CreationCollisionOption.ReplaceExisting);

Or use it to open an existing file:

var tempFile = await tempFolder.GetFileAsync("TempFileName.tmp");
