            {
                if (myIsolatedStorage.FileExists(delPath))
                {
                    myIsolatedStorage.DeleteFile(delPath);
                    MessageBox.Show("File is Deleted..!!");
                }
                else
                    MessageBox.Show("There is no file is exists");
            }
            else
            {
                MessageBox.Show("There is no Folder is exists");
            }

        }
        catch (Exception ex)

            MessageBox.Show(ex.ToString());

Perhaps, the file, you're trying to delete, is still in usage. Your application should have no open files or references to files that you are trying to delete.
