I'm too busy right now to spend time on this one but from a quick glance, the proposed addExtension and removeExtension  looks very strange. I think it would be useful to show some examples using them to justify why are needed. Also write out some candidate method names. A Path is immutable so I don't think you want methods with names like addXXX or removeXXX as the resulting usages will look like they mutate the Path.
