NTFS means NT File System. It is the default file system used by Windows. Your system drive will be formatted as NTFS when you install Windows. The file size and partition size limits are so large that you won't run up against them.
It has better security and supports recovering errors quickly by changing the journal if your computer crashes, shadow copies for backups, encryption, disk quota limits, hard links, and various other features. The system partition of Windows must be NTFS.
Besides, you should note that macOS can only read from NTFS drives but can't write directly.
