== Directory Entry Table ==
The directory entry table is an array of the entry type shown below. It describes the directory hierarchy of the file system. There are two variants of the directory entry type.

The 0-th entry of the array is always a dummy entry, which functions as the head of the dummy entry linked list. The 1-st entry of the array is always the root. Therefore maximum entry count is two more than maximum directory count. Dummy entries are left there when deleting directories, and reserved for future use.
