FAT32 has a 4GB maximum file size restriction. Does the
same thing happens to the NTFS system?

Here are the limitations:

FAT16-MaxFileSize: 2^32 minus 1 bytes (approx. 4,2GB)
FAT16-MaxVolumeSize: 4GB
FAT16-MaxFilesPerVolume: 2^16 (65536)

FAT32-MaxFileSize: 2^32 minus 1 bytes (approx. 4,2GB)
FAT32-MaxVolumeSize: 32GB / 127.53 GB
FAT32-MaxFilesPerVolume: approx. 2^22 (4194304)

NTFS-MaxFileSize: theoretical: 2^64 - 1 KB (approx. 17179869184 GB),
NTFS-MaxFileSize: implemented: 2^44 - 1 KB (approx. 16384 GB)
NTFS-MaxVolumeSize: theoretical 2^64 clusters (16 exabytes (EB))
NTFS-MaxVolumeSize: implemented 2^32 clusters (2 TB)
NTFS-MaxFilesPerVolume: 2^32 - 1 (4294967295)
