In an operating system, the data structure that is typically used for directory information is a Hash table.

Here's why:

1. Linked List: This is not typically used for directory information because searching for a file in a linked list would require traversing the entire list, which can be time-consuming.

2. Sorted List: While a sorted list could potentially make searching for files faster, it would slow down the process of adding new files to the directory, as the list would need to be re-sorted each time.

3. Hash Table: This is the most commonly used data structure for directory information. In a hash table, a unique key (in this case, the file name) is used to determine the location of the data (the file information). This allows for very fast retrieval of file information, regardless of the size of the directory.

4. Linked Binary Tree: While this could potentially be used for directory information, it would not be as efficient as a hash table. Searching for a file in a binary tree requires traversing the tree, which can be slower than a hash table lookup.
