The New Technology File System (NTFS)
is the child of HPFS (High Performance File System) that was born with
OS/2 Lan Man.
The last O/S that supported HPFS
was NT 3.51. Beginning with NT 4, it was possible to convert to NTFS
from either FAT 16 or HPFS. It could not create a HPFS volume.
NT4 can create a FAT 16 volume,
(up to 4 GB ), since it doesn't need FDISK. Frequently, you will see
NTFS4 referred to simply as NTFS. The 4 got hung on the end with Windows
2000, when a new and improved version of NTFS was introduced in Windows
There are a great many features of
NTFS that give good reasons to use this over FAT. File integrity is
greatly increased, and guarding against a flaky hard drive may be a
great reason for choosing NTFS over FAT anything.
NTFS File Structure Support
NTFS 4 supports FAT 16, NTFS 4 and CDFS.
Another reason for the existence of NTFS is the ability to hold on to more than the 4 file attributes available in FAT (archive, hidden, system, read-only). NTFS has a greatly expanded indexing system, which allows for security attributes to be attached to each file. This can protect sensitive data from prying eyes, if the users login access does not allow reading of the file, they cannot read the file.
The down side to all this extra stuff is the indexing system (called the Master File Table or MFT) is so huge, it cannot fit on a 1.44 MB floppy.
Lost and Restored
Should files be backed up (saved) from NTFS and restored to a FAT based drive, the extra data, such as; security information is lost. Only the 4 file attributes and long file names will be transferred.
NTFS 4 allows for compression of data at the volume, directory or file level.
