Abstract
A method and system are described for reducing search for data in a directory scheme employing hash tables. The method involves compacting directory entries in a manner in which the directory entries will gradually migrate and concentrate at the highest level hash tables which coincide with early blocks in a hash table sequence representing the directory.
