Key Features of the Windows File System
1. Drive Letter Assignment
Unlike Linux, Windows assigns letter labels (e.g., C:\, D:\) to each storage device, making it easier for users to identify partitions and drives.
2. File System Types
Windows supports multiple file systems, including:
NTFS (New Technology File System): Known for advanced features such as encryption, journaling, and large file support.
FAT32 (File Allocation Table 32): Commonly used for smaller drives and cross-platform compatibility.
exFAT: Optimized for external drives requiring large file sizes.
3. Hierarchical Structure
Files and directories are organized hierarchically, starting from the root directory of each drive (e.g., C:\).
4. Attributes and Permissions
Files and folders in Windows have attributes like read-only, hidden, and archive, which can be adjusted based on user needs. NTFS also supports advanced permissions for user and group access control.
