Difference between FAT 32 and NTFS file system?

FAT32 and NTFS both are file systems used by windows operating system, to store files in hard disks.

FAT32 can not hold files more than 2GB, because in the background it takes more space to store files than the actual requirement. For example to store a 2KB file, it requires 32KB. But works on multiple operating system.

NTFS means NT File Management System, works only on a single operating system.
