File System

A method of organizing and storing files on a computer's storage devices, such as hard drives or solid-state drives.

Directories

Containers used to organize files and other directories in a hierarchical structure.

Subdirectories

Directories that are contained within other directories.

Files

Collections of data that are stored on a computer's storage devices and can be accessed and manipulated by software.

File Types

Categories or formats of files, such as text files, image files, audio files, video files, etc.

File Permissions

Settings that determine who can access, modify, or execute a file, and what actions they can perform on it.

Read Permission

Permission that allows a user to view the contents of a file.

Write Permission

Permission that allows a user to modify the contents of a file.

Execute Permission

Permission that allows a user to run or execute a file as a program or script.

File Operations

Actions that can be performed on files, such as creating, opening, closing, reading, writing, deleting, and renaming.

File System Organization

The structure and layout of files and directories within a file system.

File System Hierarchy

A hierarchical structure that organizes files and directories, typically starting with a root directory.

Root Directory

The top-level directory in a file system, which contains all other directories and files.

File System Path

A string of characters that specifies the location of a file or directory within a file system.

Absolute Path

A file system path that specifies the exact location of a file or directory from the root directory.

Relative Path

A file system path that specifies the location of a file or directory relative to the current working directory.

File System Management

The process of organizing, maintaining, and optimizing a file system, including tasks like creating, deleting, and resizing partitions.

File System Security

Measures and mechanisms in place to protect files and directories from unauthorized access, modification, or deletion.

File System Permissions

Access rights granted to users or groups for files and directories, typically defined by read, write, and execute permissions.

File System Encryption

The process of encoding files and directories to prevent unauthorized access, ensuring data confidentiality.

File System Backup

The process of creating copies of files and directories to protect against data loss in case of hardware failure, accidental deletion, or other disasters.

Full Backup

A backup that includes all files and directories in a file system.

Incremental Backup

A backup that includes only the files and directories that have changed since the last backup.

Differential Backup

A backup that includes only the files and directories that have changed since the last full backup.

File System Recovery

The process of restoring files and directories from a backup to recover data after a loss or corruption.

File System Check

A utility that scans a file system for errors and inconsistencies, and attempts to fix them.

File System Fragmentation

The condition where files and directories are divided into small, scattered fragments on a storage device, leading to decreased performance.

Defragmentation

The process of reorganizing fragmented files and directories on a storage device to improve performance.

File System Mounting

The process of making a file system accessible and available for use by the operating system and applications.

File System Unmounting

The process of detaching a file system from the operating system, making it inaccessible and unavailable for use.

File System Format

The process of preparing a storage device to be used by a file system, including creating the necessary data structures and metadata.

File System Types

Different types of file systems, such as FAT32, NTFS, ext4, HFS+, etc., each with its own features and limitations.

File System Quotas

Limits set on the amount of disk space a user or group can consume within a file system.

File System Journaling

A technique used by some file systems to record changes to the file system in a journal, allowing for faster recovery in case of system crashes or power failures.

File System Compression

The process of reducing the size of files and directories to save disk space, typically using algorithms that remove redundant or unnecessary data.

File System Virtualization

The process of abstracting and isolating file systems from the underlying physical storage devices, allowing for more flexible and efficient management.

File System Sharing

The ability to access and use files and directories from multiple computers or users, typically over a network.

File System Network Protocols

Protocols and technologies used for sharing files and directories over a network, such as NFS, SMB/CIFS, FTP, etc.

File System Access Control

Mechanisms and policies in place to regulate and restrict access to files and directories, ensuring data security and privacy.

File System Auditing

The process of monitoring and recording file system activities, such as file accesses, modifications, and deletions, for security and compliance purposes.

File System Troubleshooting

The process of identifying and resolving issues or problems related to file systems, such as file corruption, disk errors, or permission conflicts.

File System Error Messages

Messages or notifications displayed when a file system encounters an error or issue, providing information for troubleshooting and resolution.

File System Maintenance

Regular tasks and activities performed to ensure the optimal performance, reliability, and integrity of a file system.

File System Monitoring

The process of observing and tracking file system activities, performance metrics, and resource utilization to detect and prevent issues.

File System Upgrade

The process of replacing an existing file system with a newer version or different type, often to take advantage of new features or improvements.

File System Migration

The process of transferring files and directories from one file system to another, typically to upgrade or consolidate storage infrastructure.

File System Backup and Recovery

Strategies, techniques, and tools used to create backups of files and directories, and restore them in case of data loss or system failure.

File System Performance Optimization

Techniques and practices aimed at improving the speed, efficiency, and responsiveness of a file system, such as defragmentation or caching.

File System Scalability

The ability of a file system to handle increasing amounts of data, users, or workload without significant degradation in performance or functionality.

File System Reliability

The measure of a file system's ability to consistently and accurately store, retrieve, and protect data, without errors or failures.

File System Availability

The measure of a file system's ability to be accessible and usable by users and applications, without interruptions or downtime.

File System Integrity

The assurance that files and directories have not been tampered with or modified without authorization, ensuring data accuracy and trustworthiness.
