can me making mistake?

the code perfect, problem silverlight uses "isolated storage" storing files, is, name implies, isolated storage. file or directory created application accessible application.

i think emulator storing isolated storage files in memory, since doesn't have keep them after restart. if want see inside application's isolated storage use tool wp7 explorer: http://wp7explorer.codeplex.com/
