Typically a leading "." (for the directories "." and "..") would not be considered the start of an extension.  (As was spec'd earlier).  Both "/." and "/.." have an empty extension.

Agreed.

I would suggest that `removeExtension()` would be more useful if it removed the final ".", if any.
`addExtension("txt")` would be smart enough to handle both "abc." and "abc" resulting in "abc.txt”.

I think that would work.

Aside from “.”, “..”, a leading “.” to denote hidden files on UNIX, and various edge cases to be ignored for the moment, I look at the “.” as a separator character somewhat analogous to File.separatorChar.

Thanks,

Brian
