The other way, which I personally take as a better way, is to make it truely OO. I see an Openner class, and two subclasses of this Openner class: PlainOpenner and ZippedOpener. Both PlainOpenner and ZippedOpenner has their own open method.

After you detect the type of the file, base on the type, either new a PlainOpenner or a ZippedOpenner. When you call open(), it would be resolved to the appropriate one.

Seems to me, this gives a better application structure.
