Unlike previous filesystem versions like FAT or FAT32 the NTFS (New Technology File System) is an enhanced file system offering better performances and data protection.

The NTFS filesystem was specially developed by Microsoft for the Windows NT operating system and later it proved to be supported by the newest releases of operating systems like Windows 2000, Windows XP, Windows Server 2003, and the most recent operating system Windows Vista.

In a nutshell, NTFS is one of the most reliable and secure filesystems developed by Microsoft. The base element of NTFS is the Master File Table (MFT) which is an index of all files keeping track of the contents of the NTFS volume. It is advisable to use at least a 50 MB space for a partition as the New Technology File System allocates 5 MB overhead space.

Some other main features of the NTFS filesystem are the support of long filenames, recoverable file system, protection against power outage or system failure, support for compression of files or folders, provides local security, support for spanning volumes.

There are many versions for the NTFS filesystem like:
•    v1.0
•    v1.1
•    v1.2
•    v3.0
•    v3.1
•    …..

Each new version comes with new improvements with new features from which the latest ones for Windows Vista are the Transactional NTFS and self-healing functionalities.
The new 5.0 NTFS version comes with even more features like Dynamic Disk support and Disk quotas.

For those who are working with large volume files usually video files, the NTFS offers an outstanding performance supporting file sizes up to 4GB and an increased performance of new large volume hard drives.

The FAT32 file allocation table was introduced in 1996 together with the improved Windows 95 OSR2 operating system. The newly developed file system made it possible to create hard disks with larger storing capacities than its predecessor the FAT16 which allowed a maximum of 2GB of data. The FAT32 supports large amounts of data up to 2 terabytes and the space is being used more efficiently with smaller clusters.

The new filesystem made possible to relocate the root directory and the boot record has been expanded for backup purposes of critical data. The root directory can be placed anywhere on the hard drive making it more flexible.

FAT32 was developed to be compatible with the existing file architecture used by Windows’95, with data structures and API interfaces so that most applications, drivers and utilities won’t be affected and should be working properly.

Performance of most applications has also increased thanks to the new file system but there are also a few applications which encountered a slight degradation of their performance.

FAT is the acronym for File Allocation Table which is one of the best known methods to keep track of the contents of a disk used by the Windows operating systems. It was invented in 1977 by Microsoft and initially was the solution to store data on floppy disks.
The FAT filesystem was used by the MS-DOS (Microsoft Disk Operating System), developed by Microsoft. We can distinguish three types of File Allocation Tables:

FAT12 – it is a 12-bit binary file system and the oldest FAT type
FAT16 – it uses a 16-bit binary file system (there are still PCs running Windows 3.1 or 95 in which the hard drive uses FAT16 filesystem)
FAT32 – an improved file allocation table which uses 28-bit binary system
