您可以刪除隔離儲存盤案內的目錄和檔案。 在存放區中，檔案和目錄名稱依賴於作業系統，並被指定為相對於虛擬檔案系統的根目錄下。 在 Windows作系統上，它們不區分大小寫。
類別 System.IO.IsolatedStorage.IsolatedStorageFile 提供兩種方法來刪除目錄和檔案： DeleteDirectory 和 DeleteFile。 IsolatedStorageException如果您嘗試刪除不存在的檔案或目錄，就會擲回例外狀況。 如果您在名稱中包含通配符， DeleteDirectory 則會 IsolatedStorageException 擲回例外狀況，並 DeleteFile 擲回例外狀況 ArgumentException 。
如果目錄包含任何檔案或子目錄，此方法 DeleteDirectory 就會失敗。 您可以使用 GetFileNames 和 GetDirectoryNames 方法來擷取現有的檔案和目錄。 如需搜尋存放區虛擬文件系統的詳細資訊，請參閱 如何：在隔離儲存區中尋找現有的檔案和目錄。
