/// The first problem might occur when calling AddDirectory() on a directory

/// process, but not locked, and a range lock has been taken on the file.

/// <see cref="ZipProgressEventType.Error_Saving"/>. A typical use of this option:
/// a GUI application may wish to pop up a dialog to allow the user to view the
/// error that occurred, and choose an appropriate action. After your
/// processing in the error event, if you want to skip the file, set <see
/// cref="ZipEntry.ZipErrorAction"/> on the
/// <c>ZipProgressEventArgs.CurrentEntry</c> to <c>Skip</c>. If you want the
/// exception to be thrown, set <c>ZipErrorAction</c> on the <c>CurrentEntry</c>
/// to <c>Throw</c>. If you want to cancel the zip, set
/// <c>ZipProgressEventArgs.Cancel</c> to true. Cancelling differs from using
/// Skip in that a cancel will not save any further entries, if there are any.
/// (For COM clients, the value of this enum is a 3.)
