Does anybody know how the NSWorkspace method -isFilePackageAtPath: determines whether the file at the path is a bundle or not? Does it just look at the directory structure only or does it read some files? Is there a way to find out?
I think it's a combination of (a) does the directory look like a bundle, i.e. contains a "Contents" directory; and (b) does the directory name's extension match that of a bundle-based type registered with Launch Services. (This is why sometimes if you see a bundle-based document for an app you don't have, it looks like a folder.)
The LaunchServices documentation might explain in detail. —Jens
