Maybe the download was corrupt or you accidentally renamed the extension. I'd try downloading from a different spot. But before you do any of this, make certain you've run HL at least once. Doing that actually unpacks the .GCF files and creates the HL directory. And don't install with steam running (or if you do, restart steam after the install since it won't see the game until you do this).

Go into your folder and verify whether ESF has been installed in the correct map or not.
