The Finder and all its functionality was ported to Cocoa in 10.6. All related functionality has eventually made its way into Cocoa: NSWorkspace, NSURL, NSFileManager, and NSFileCoordinator. The Carbon file management APIs are long, and thankfully, dead.

Wow, that's an interesting bit of trivia. I didn't realize old Finder code (well, Carbon stuff) was kicking around that long.
