Well, directories -are- a single file so it makes sense that the file
size refers to exactly the directory and not its contents. Besides,
for the general case of looking at files/folders in a particular
directory, you could get all the attributes quickly without paying a
time penalty to recursively calculate the total file size until you
decide that you actually need that information.
As for choosing to use Carbon, making that decision based on what the
Finder is or isn't doing is not very relevant. Not everything has
been made "native" Cocoa, or a Carbon solution might be better for a
particular task. If you don't want to see procedural calls in your
general code, just wrap the Carbon bits in a Cocoa method wrapper and
claim blissful ignorance of the implementation. :)

Thank you I.S. and all who replied! :-)
It's my understanding that [NSFileManager
fileAttributesAtPath:traverseLink:] will do fine for a single file
but for directories it won't include the sizes of the
subdirectories as Finder does. That's what I got in my testing as
well but maybe I'm missing something?
As for not using Carbon I suppose there's no reason I can't use
it. I was just thinking with Finder going away from Carbon and
since I'm just learning Cocoa I was trying to avoid it if I could.
But if it's the best way I can use it...
Thank you very much,
Rick

My apologies if this has been answered before but isn't there a
simple way to get the file size as it shows under Size in Finder
without using Carbon and without enumerating the directory? My
understanding is NSFileSize will not do it?
Have you tried searching the archives? How about Google?
See -[NSFileManager fileAttributesAtPath:traverseLink:] ... it
includes a fileSize attribute.
