> Since the leaf level directory doesn't store the metadata directories file, 
> while reading summary if the directories cache file is not present, it is 
> assumed that the cache is possibly corrupt and reading of the summary cache 
> file is skipped. Metadata directories cache file should be created at the 
> leaf level.
