Any FAT and NTFS.
NTFS
NTLDR is indeed a key boot file in Windows 2000 and all of the Windows operating systems since Windows NT. A machine will not boot without that file.
Windows NT4 Service Pack4 and Windows XP Professional
There are like hundreds of them, I cannot list each on of them now.
NetBSD, Windows, and Linux each support both FAT and NTFS file systems.
File Name Extension Associations in Windows 2000 is displayed by the Windows Association parameters. Microsoft support can help you with this. You can get live help at Microsoft Support.
NTFS supports disk quotas. The varieties of FAT do not. UDF and ISO9660 and similar removable media file systems do not support disk quotas. NFS and SMB network file systems will honor any disk quotas that their server enforces.
Lots of files are common between the three systems. ddraw.dll, comctl32.dll, nt.dll, etc...

The file systems supported by Windows XP and Windows Vista are essentially the same. However, Windows Vista does not support booting from FAT32 partitions, and Windows XP does not support Windows Vista's Shadow Copy feature (which makes automatic backups of files) and will delete the backups if it accesses an NTFS Windows Vista partition.
