NTFS and Drive Letters

Introduction to NTFS
  - NTFS does not include traditional file permissions.
  - NTFS employs journaling to ensure data integrity.
  - The primary function of NTFS is to create the root directory, which is the starting point for the file hierarchy.

CLI Interactions
  - Users do not see the underlying commands when they interact with a GUI.
  - While using a GUI (e.g., clicking icons), the user is performing operating system (OS) commands without awareness.
  - For example, when a user creates a root directory via the GUI, it corresponds to an initial command for file access in the CLI.

System Path for Accessing Files
- The access point for files begins with system designations, particularly the C: drive.
- NTFS manages a structure known as the Master File Table (MFT), which serves as an index/database for file locations and their attributes.
Drive Letter History
  - The letters A and B were historically designated for floppy disk drives.
  - The C drive became standard for the first hard drive in the system hierarchy.
  - Summary of drive letter assignments:
    - A: Floppy Disk
    - B: Floppy Disk
    - C: First Hard Drive
