I have no idea which internal tricks the "dir" command uses to become that 
fast*, but do remember that the commandline "dir" doesn't sort.  It just 
shows the files in order of how they appear in the filesystem.  Most Windows 
oriented "dir" methods will sort on the filename.

* it could just iterate over the records in a retrieved raw cluster, 
bypassing the API the rest of us have to use.

Also, I've written directory traversal code for both DOS as well as Windows, 
and if I did not output anything it was always quite fast.  iow, the 
bottleneck was more often than not the storing of the retrieved data 
somewhere (screen, list/treeview, file).
