I have never tested the setDefaultSuffix function out, so I was just giving you what I thought it was supposed to do. We do not use this function, instead we just add the extension if it is not there like I suggested you would have to do with the static function. I am guessing you will have to do the same thing. Here is an example of what to do:

That method works fine, thanks. However, since we both expected the
same thing from the defaultSuffix, we should probably alert the devs
so they can clarify the documentation, don't you think?
