What is a File System? FAT32 vs. NTFS vs. exFAT

A file system is a method used by an operating system to organize, store, and retrieve data on storage devices like hard drives, SD cards, and USB flash drives. It determines how files are structured and accessed within folders.

Without a file system, data would be stored as raw bits, making it impossible for the OS to locate specific files efficiently.

Popular Types of File Systems

1. FAT32 (File Allocation Table 32)

📅 Introduced: 1996
🌍 Known as: Universal file system
💾 Commonly Used In: Memory cards, USB drives, external storage devices

✅ Advantages:

• Compatible with almost all operating systems (Windows, macOS, Linux, game consoles, cameras, etc.).
• Works well for small-sized storage devices.

❌ Limitations:

• Maximum file size: 4GB (cannot store larger files).
• Maximum partition size: 2TB.
• Lacks security features like encryption and file permissions.

2. NTFS (New Technology File System)

📅 Introduced: 1993
💻 Commonly Used In: Windows operating system drives (C:, D:)

✅ Advantages:

• Supports large files and partitions (no 4GB limit).
• Includes file permissions, encryption, and security features.
• Provides faster read/write speeds and better data recovery.

❌ Limitations:

• Limited compatibility (mostly works on Windows; macOS can read but not write without extra software).
• Not the best choice for external drives that need to work across multiple devices.

3. exFAT (Extended File Allocation Table)

📅 Introduced: 2006
🚀 Best for: Large file storage on external drives and SD cards

✅ Advantages:

• Supports files larger than 4GB (ideal for movies, backups, etc.).
• Works on Windows and macOS without additional software.
• Faster than FAT32, with better efficiency for flash storage devices.

❌ Limitations:

• Not as widely supported as FAT32 on older devices (e.g., some gaming consoles and older operating systems).
• Lacks advanced security features like NTFS.

How to Check Your File System?

To find out which file system your drive is using:

1. Right-click on the drive (USB, SD card, hard drive).
2. Select Properties.
3. Look for File System, where it will show FAT32, NTFS, or exFAT.

Which File System Should You Use?

✔ Use FAT32 for small USB drives and devices needing maximum compatibility.
✔ Use NTFS for Windows system drives and secure storage.
✔ Use exFAT for external hard drives and SD cards storing large files.
