Try this:  open a directory window for the first time under the A/UX Finder.  
Close it.  Now open it again.  It's much faster!  That's because A/UX needs 
to compute the extended Macintosh file attributes for each UNIX file in a 
directory.  This information is stored away in a database, so on successive 
accesses to that directory, the information is already there.
