You could also use getResourceValue:forKey:error: on the URLs with 
NSURLFileResourceIdentifierKey as the key, and compare the resulting objects.

The one caveat of this is that the file resource identifiers will be equal if 
the files have the same inode, so comparing two hard links of the same file 
(for example, /bin/rm and /bin/unlink) will turn up the result that the files 
are equal, despite having different paths. If that isn't an issue, though, then 
this is a pretty consistent way to compare files.
