Introduction to Filesystems
A filesystem is a fundamental component of an operating system that manages how data is stored and retrieved on storage devices. Traditional filesystems organize and track files on a single storage device, providing a logical structure of directories and files that users and applications can interact with.
Key Functions of Traditional Filesystems:
- Organizing files and directories
- Allocating storage space
- Tracking file metadata (size, permissions, timestamps, etc.)
- Providing APIs for file operations (create, read, write, delete)
Examples of Traditional Filesystems:
- FAT32 and NTFS for Windows
- ext4 and XFS for Linux
- APFS for macOS
