@jhwgh1968 @grishka @tubetime Both existed, just in different DOS versions - early versions just had Abort, Retry, Ignore, whilst later versions offered different choices under various conditions.
I think 3.3 was the point at which it changed; 3.2 always offered Ignore but 3.3 and up rarely did, preferring the new Fail option. Very occasionally you'd be offered all four options!
