B-trees are balanced tree data structures that maintain sorted data and allow for efficient insertion, deletion, and search operations, making them ideal for use in databases and file systems. They are characterized by nodes with multiple children and are designed to minimize disk I/O operations by keeping related data in contiguous blocks.

A file system is a method and data structure that an operating system uses to manage files on a disk or partition, determining how data is stored and retrieved. It provides a way to separate the data into pieces and give each piece a name, making it easier to organize, retrieve, and manipulate files efficiently.
