"…a file system or filesystem is a method and data structure that the operating system uses to control how data is stored and retrieved."
The management of files and directories within an operating system. This includes file naming, storage allocation, file access, and file sharing.
File Systems: The different types of file systems such as FAT, NTFS, Ext, etc., and how they organize and manage data in the OS.
Partitioning: Understanding how to create, modify and manage partitions within a hard drive or storage device.
Mounting and Unmounting: The process of attaching and detaching storage devices and making them available to the OS.
Allocation Methods: Choosing how the file system makes use of available space on a storage device, including contiguous allocation, linked list allocation, and indexed allocation.
Directory Structures: Understanding the hierarchy and organization of directories and files within an OS.
Disk Management Tools: How to use various tools to manage file systems and storage devices, including command-line tools and GUI-based tools.
File Compression: Understanding how to compress files to save space and reduce transfer time.
File Permissions: Understanding and controlling access to files on a file system.
Backup and Recovery: Understanding how to create backups of files and directories and how to recover them in case of data loss.
RAID (Redundant Array of Inexpensive Disks): Learning about various RAID configurations to enhance data reliability and performance.
FAT (File Allocation Table): Used primarily for floppy disks and older hard drives, this file system uses a table to keep track of which clusters on the disk are free and which are in use.
NTFS (New Technology File System): Used primarily in modern versions of Windows, NTFS supports larger file sizes and partition sizes than FAT and provides a range of features such as file compression, encryption, and built-in security permissions.
HFS (Hierarchical File System): Used in macOS versions up to 9.2, this file system organizes files in a hierarchical tree structure and uses resource forks to store metadata about files.
HFS+ (Hierarchical File System Plus): Used in macOS versions 10.0 to 10.12, HFS+ improves on HFS by increasing hard disk capacity and supporting Unicode.
APFS (Apple File System): Used in macOS versions 10.13 and later, APFS is designed to work with solid-state drives and provides features such as cloning, snapshotting, and atomic safe-save operations.
EXT (Extended File System): Used in Linux, EXT2, EXT3, and EXT4 are different versions of this file system, which uses an inode-based architecture to store metadata about files and directories.
ZFS (Z File System): Used in some Unix-based systems, such as Solaris and FreeBSD, ZFS is a modern file system that provides features such as data compression, snapshotting, and flexible storage pool management.
ReFS (Resilient File System): Used in some versions of Windows Server, ReFS provides features such as data integrity and automatic repair, and is optimized for large-scale data storage.
exFAT (Extended File Allocation Table): Used for flash drives and SD cards, exFAT supports larger file sizes than FAT and supports Unicode filenames.
Btrfs (B-tree File System): Used in some Linux distributions, Btrfs provides features such as data deduplication, snapshotting, and native support for RAID configurations.
JFS (Journaling File System): Used in some Unix-based systems, JFS provides data journaling and other features to ensure data consistency in the event of system crashes or power failures.
XFS (Extended File System): Used in some Unix-based systems, XFS is optimized for large-scale data storage and provides features such as data journaling and support for multiple disk volumes.
UDF (Universal Disk Format): Used for optical discs such as CDs and DVDs, UDF is a cross-platform file system that supports larger file sizes than ISO 9660.
ISO 9660: Used for CD-ROMs, this standard defines the filesystem used to store data on the disc, including a file and directory hierarchy, as well as file attributes and metadata.
CDFS (Compact Disc File System): Used for older CD-ROMs, CDFS is a simple file system that uses a table of contents to organize files on the disc.
"Without a file system, data placed in a storage medium would be one large body of data with no way to tell where one piece of data stopped and the next began, or where any piece of data was located when it was time to retrieve it."
"By separating the data into pieces and giving each piece a name, the data are easily isolated and identified."
"Taking its name from the way a paper-based data management system is named, each group of data is called a 'file'."
"The structure and logic rules used to manage the groups of data and their names is called a 'file system.'"
"There are many kinds of file systems, each with unique structure and logic, properties of speed, flexibility, security, size and more."
"Some file systems have been designed to be used for specific applications. For example, the ISO 9660 and UDF file systems are designed specifically for optical discs."
"File systems can be used on many types of storage devices using various media."
"Other kinds of media that are used include SSDs, magnetic tapes, and optical discs."
"In some cases, such as with tmpfs, the computer's main memory (random-access memory, RAM) is used to create a temporary file system for short-term use."
"Some file systems are used on local data storage devices; others provide file access via a network protocol (for example, NFS, SMB, or 9P clients)."
"Some file systems are 'virtual,' meaning that the supplied 'files' (called virtual files) are computed on request or are merely a mapping into a different file system used as a backing store."
"The file system manages access to both the content of files and the metadata about those files."
"It is responsible for arranging storage space; reliability, efficiency, and tuning with regard to the physical storage medium are important design considerations."
