I think you have a couple of options, neither terribly satisfactory:

A) Use the .filename property to work your way through the wrappers and build 
up the expected URL/path of the file. Then query that to know if it's a package.

B) Grab NSFileSystemFileNumber from the package, and use it to locate the file 
on disk, querying that.
