In that case I suggest you use an FSIterator with
FSGetCatalogInfoBulk(). There have been quite a few posts on this
subject on this list. Search the archives for FSGetCatalogInfoBulk().
FSGetCatalogInfoBulk() is probably the fastest method for directory
enumeration if you need any kind of metadata about the file (name,
directory, permissions, whatever).
Conversely, directoryContentsAtPath is probably the slowest method to
enumerate directories.

I call it as a reaction to a user selecting a file or a directory. I
list its siblings.
The list may be very long. I for one always have many items in the
trash. When I hit that I am in for 10-20 seconds of beachball.
You may see this method in action in the Apple provided sample code:
SimpleBrowser. You will see that it is way slower to browse the file
system than the Finder is.
