What is the difference between NTFS & FAT?

NTFS (New Technology File System) is the primary file system used in Windows operating system that supports larger file sizes and hard drives. It is the newest file system created by Microsoft and is the default for almost every modern hard drive, and SSDs. It has support for file compression, long file names, and no reasonable file size limitations.

FAT (File Allocation Table) is an older type of file system that is universally supported by all operating systems. It is normally pre-installed on all the USB drives and has a big limitation of supporting only file size up to 4GB.
