[USB Flash Basic] What are common file systems for USB flash drives, and which should I use?

The file system determines how data is stored and organized on the drive. Different file systems offer varying compatibility and feature sets.

• FAT32 (File Allocation Table 32):
  • Pros: Most compatible across different operating systems (Windows, macOS, Linux) and devices (smart TVs, gaming consoles, car stereos).
  • Cons: Maximum single file size limit of 4GB. This means you cannot copy a file larger than 4GB to a FAT32 formatted drive. Maximum partition size is typically 32GB (though some tools can format larger).
  • Usage: Ideal for broad compatibility, small files, and older devices.
• exFAT (Extended File Allocation Table):
  • Pros: Cross-platform compatible (Windows, macOS, modern Linux) and no practical file size or partition size limits for common use.
  • Cons: Less compatible with very old devices compared to FAT32.
  • Usage: Recommended for general use, especially if you need to transfer files larger than 4GB between different operating systems.
• NTFS (New Technology File System):
  • Pros: Windows native file system. No practical file size or partition size limits. Supports advanced features like file compression, encryption, and permissions. More robust for large internal drives.
  • Cons: Read-only on macOS by default (requires third-party software for full write access). Limited or no native support on many other devices (e.g., smart TVs).
  • Usage: Best if the drive will be primarily used with Windows computers and you need to store very large files or utilize Windows-specific features.

Recommendation: For most users, exFAT offers the best balance of cross-platform compatibility and support for large files. If you exclusively use Windows and need advanced features, NTFS is an option. For maximum compatibility with older devices, FAT32 might be necessary, but be aware of the 4GB file size limit.
