What are File Systems? Basic Concepts

File systemsFile systems are the fundamental structures that determine how data is organized, stored, and accessed on a storage device. They define how files and directories (folders) are managed on storage media such as a computer's hard drive, SSD, or USB memory stick. These systems provide a framework for the operating system to read and write data meaningfully. An effective file system must optimize performance while maintaining data integrity.

File systems not only store files but also store information about file properties (creation date, size, permissions, etc.), called metadata. This metadata helps manage and locate files efficiently. Different file systems can support different metadata attributes, resulting in significant differences in compatibility and functionality.

Basic Properties of File Systems

• Data organization and storage
• File and directory management
• Access permissions and security
• Data integrity and recovery mechanisms
• Performance optimization
• Metadata management

Different operating systems support different file systems. For example, Windows typically uses NTFS (New Technology File System), while Linux uses file systems such as ext4 (Fourth Extended File System) or XFS. macOS uses APFS (Apple File System). Each file system has its own advantages and disadvantages, and it's important to choose one based on your usage scenario.

File System	Developer	Key Features	Areas of Use
NTFS	Microsoft	Security, compression, encryption	Windows operating systems, external disks
ext4	Linux Foundation	Performance, reliability, large storage support	Linux operating systems, servers
APFS	Apple	Speed, security, SSD optimization	macOS, iOS devices
ZFS	Sun Microsystems (Oracle)	Data integrity, RAID support, snapshots	Servers, NAS devices, big data storage

The choice of file system directly impacts performance, security, and compatibility. For example, a file system designed to store large files may perform differently than one optimized for storing small files. Similarly, in an environment requiring security measures, a file system with encryption and access control capabilities should be preferred. In the following sections, we will examine each of these file systems more closely, detailing their key differences and applications.
