The IsolatedStorageProvider uses the PersistenceManager's storage, which holds all of the controls marked with the StorageId propery. You can access this storage with the PersistenceManager.GetStorage()
static method. If you want to save only certain files, you could remove the control that are not to be saved from that storage and call SaveToStorage method.
In regards to deleting only specific settings, you can access the isolated storage with the GetIsolatedStoreOverride
method of the IsolatedStorageProvider. Please note that this method is protected and you have to subclass the provider to use it. For example, you can extend this class in the following way:
public class IsolatedStorageProviderEx : IsolatedStorageProvider
public void DeleteFile(string file)
var store = this.GetIsolatedStoreOverride();
Please note that the file's extension is ".bin". With the upcoming versions, the extension will be exposed as a property of the provider.
