Windows 2000 -- a file system for everyone

Windows 2000 supports no less than five different file systems.
NTFS 5 is the latest version of NTFS and is intended to be the main file system with Windows 2000, and any NTFS volumes on the system will automatically be upgraded to NTFS 5. Systems running Windows NT 4 can read and write NTFS 5 file systems with the installation of Service Pack 4. NTFS 5 allows volumes of up to 16 terabytes, and other advanced features.
UDF is the Universal Disk Format, designed for supporting DVDs, newer CD-ROMs and other optical disks. CDFS, the Compact Disk File System, does basically the same job as the UDF, which is replacing it.
FAT32 is also used by Windows 98 and dual-booting machines running Windows 98 and Windows 2000 should use it. Windows 2000 can only create FAT32 volumes up to 32 gigabytes, although it can read and write larger volumes created with Windows 98.
Windows 2000 also continues to support the older 16-bit FAT file system, which goes back to the days of MS-DOS. However this is only for backwards compatibility. Microsoft says there won't be any more enhancements to FAT16. Administrators should strongly consider migrating data to newer systems.
For more information on Windows 2000 file systems and their uses, see the Windows 2000 guide on the Microsoft Web site.
