Paths "through" alias files make no sense.  Nothing else in the system will 
resolve an alias there, so nothing will ever produce such a path.  If your code 
is producing such paths, you should fix it, because nothing else will be able 
to process them.

You should construct NSURL objects from the two paths, use 
-getResourceValue:forKey:error: with the key NSURLFileResourceIdentifierKey to 
get the resource ID for each, and then use [resourceID1 isEqual:resourceID2] to 
determine if the two paths refer to the same file-system object.
