The dynamic range -configuration consists of two values :

    -
  1. FAT_DirCacheSizeMin specifies -the minimum size of global cache to be allocated to the directory cache on -a drive.

  3. FAT_DirCacheSizeMax specifies -the maximum size of the global cache to be allocated to the directory cache -of a drive.
