Difference Between FAT32 and NTFS


Key Differences

FAT32, an older file system, is compatible across various platforms, but it lacks advanced security features. It has limitations on file sizes and doesn't support file-level encryption.
NTFS, a modern file system, supports larger files and offers enhanced security features like file-level encryption, access control, and better data reliability.
FAT32's compatibility across different operating systems makes it useful for devices like USB drives but restricts file sizes to a maximum of 4GB per file.
NTFS, being the native file system for Windows, handles larger file sizes efficiently and provides better fault tolerance, supporting complex data structures.
FAT32 lacks journaling, making it more prone to data corruption or loss due to unexpected system crashes or power failures.
NTFS utilizes journaling, enhancing system reliability by keeping track of changes, reducing the risk of data loss or file corruption during unexpected events.
Limited security features in FAT32 make it vulnerable to unauthorized access compared to NTFS, which supports access control and encryption.
NTFS's support for file encryption and access control allows users to secure their data, providing better protection against unauthorized access.
FAT32 is suitable for smaller storage devices due to its compatibility, although it lacks modern features essential for data security and larger file handling.
NTFS's advanced capabilities cater to modern computing needs, offering security, scalability, and reliability, making it suitable for larger storage systems.
