Windows 2000 File System

Windows 2000 supports several File Systems, the most important of File Systems are given below:

1. FAT-16: It is the old MS-DOS file system. It uses 16-bit disk addresses, so it supports only 2 GB. It is very important for the use of a FAT-16 hard disk. If FAT-16 is lost, the data on the hard disk can’t be used because it is unable to be located. FAT16 is used in MS-DOS and low-level versions.

2. FAT-32: FAT 32 is one type of disk partition format in Windows system. It uses 32-bit disk addresses and supports disk partitions up to 2TB.

Key Features of FAT-32:

i. FAT-32 is in support of a disk of 2TB (2048GB) at most, but it’s not in support of partitions less than 512MB. Windows 2000 based on FAT-32 is in support of partitions of 32GB at most.

ii. The adoption of the smallest cluster makes Information preservation more efficient in the FAT-32 system.

iii. FAT-32 system can relocate the root directory and use FAT to back up. In addition, the boot logging of partition in FAT-32 is contained in a structure with critical data and it reduces the possibility of a system crash.

3. NTFS: It stands for New Technology File System. It was developed specifically for Windows NT and carried over to Windows 2000. It uses 64-bit disk addresses and it can support disk partitions up to 264 bytes.

The individual filename in NTFS is limited to 255 characters, path names are limited to 32767 characters. NTFS fully supports case-sensitive names. NTFS is not just a linear sequence of bytes like FAT-32. Each NTFS disk partition contains file directories bitmaps and other data structures. Each partition is organized as a linear sequence of blocks.

Key Features of NTFS:

i. Recoverability: NTFS having high recoverability from the system crashes and disk failure.
ii. Security: It provides high security among all the files.
iii. Large disks and large files: NTFS supports very large disks and very large files so it is more efficient than FAT.
iv. Multiple Data Files: In NTFS, a file is treated as a stream of bytes. It is possible to define multiple data streams for a single file.
v. General Indexing Facility:In NTF, files can be indexed by any attribute.
