hm. I wonder what it should return? for instance, what do you do with a .tar.gz?
You normally will gunzip it. Then look at the file again and now you have .tar.

I am not sure, I'm open to suggestions as to if .tar.gz should be returned as
the extension or if .gz should.

I beg to differ, the file extension is important. What kind of file am I looking
at? .zip? .gz? .html? .txt? They still play a vital role on Linux and Windows/DOS
systems. I do think the utility of returning .tar.gz or just .gz can be
discussed.

Now, also, you can easily derive the filename.ext from pathinfo by concating the
two.
