Answer / sumit
FAT (File Allocation Table) and NTFS (New Technology File
System) are both types of file systems on our operating
system. We can choose any of them, but from Windows NT
onwards, NTFS has become more popular. FAT has also got
different versions like FAT12, FAT16 and FAT32, but now
FAT32 is more prevalent of them.
What you will use in your computer will be decided on the
performance, disk size, security, reliability and so on.
You can even use both the file systems on a single
computer. Below I will discuss, some basic differences
between FAT32 file system and NTFS file system, so that you
can get some basic idea of differences between them:
1. As the performance is better in NTFS file system, it is
better to use NTFS file system if your partition is above
400 MB; whereas you should not use FAT32 file system above
400 MB because the performance of FAT32 file system
degrades as the volume increases.
2. You should use FAT32 file system if your partition is
below 400 MB, because if you use NTFS file system, the
overhead of using it will be more.
3. Maximum size of partition that you can make using FAT32
file system is 2 TB (terabytes); whereas there is not such
limitation as to now in NTFS file system.
4. Maximum file size in FAT32 file system is 2 GB
(gigabytes); whereas maximum file size in NTFS file system
is 16 TB (terabytes).
5. There is no file encryption built into NTFS file system,
so anyone can access your files using low level
programming. Whereas, in FAT32 file system file encryption
is there.
6. There is no way of formatting a floppy disk in NTFS file
system because of the overhead involved in running the file
system, but there is no such problem in FAT32 file system.
7. NTFS file system supports the all the POSIX requirement;
whereas FAT32 does not support them.
8. FAT32 file system is generally is used on Windows 95,
Windows 98, Linux and other such previous operating
systems; whereas in modern operating systems like Windows
NT, Windows XP, Windows Vista etc., NTFS file system is
more prevalent. Although you can still use FAT32 file
system on them, but performance will surely degrade.
9. Nowadays, NTFS file system is more widely used because
the storage devices (hard disks) are getting bigger and
bigger; FAT32 is less used nowadays.
So, from the above differences we can see that NTFS file
system is the file system of new world and will be more
widely used as our hard disks will become bigger and bigger!

FAT OVERVIEW
FAT is by far the most simplistic of the file systems
supported by Windows NT. The FAT file system is
characterized by the file allocation table (FAT), which is
really a table that resides at the very "top" of the volume.
To protect the volume, two copies of the FAT are kept in
case one becomes damaged. In addition, the FAT tables and
the root directory must be stored in a fixed location so
that the system's boot files can be correctly located.
A disk formatted with FAT is allocated in clusters, whose
size are determined by the size of the volume. When a file
is created, an entry is created in the directory and the
first cluster number containing data is established. This
entry in the FAT table either indicates that this is the
last cluster of the file, or points to the next cluster.
Updating the FAT table is very important as well as time
consuming. If the FAT table is not regularly updated, it can
lead to data loss. It is time consuming because the disk
read heads must be repositioned to the drive's logical track
zero each time the FAT table is updated.
There is no organization to the FAT directory structure, and
files are given the first open location on the drive. In
addition, FAT supports only read-only, hidden, system, and
archive file attributes.
NTFS OVERVIEW
From a user's point of view, NTFS continues to organize
files into directories, which, like HPFS, are sorted.
However, unlike FAT or HPFS, there are no "special" objects
on the disk and there is no dependence on the underlying
hardware, such as 512 byte sectors. In addition, there are
no special locations on the disk, such as FAT tables or HPFS
Super Blocks.
The goals of NTFS are to provide:
* Reliability, which is especially desirable for high
end systems and file servers
* A platform for added functionality
* Support POSIX requirements
* Removal of the limitations of the FAT and HPFS file
systems

Answer / soumitra
FAT (FAT16 and FAT32) and NTFS are two methods for storing
data on a hard drive. The hard drive has to either be
formatted using one or the other or can be converted from
one to the other (usually FAT to NTFS) using a system tool
NTFS is a high-performance and self-healing file system
proprietary to Windows XP 2000 NT which supports file-level
security compression and auditing. It also supports large
volumes and powerful storage solution such as RAID.
The most important new feature of NTFS is the ability to
encrypt files and folders to protect your sensitive data

Answer / sanjay dodke
The major diff. between FAT and NTFS is security, If you
have FAT partition then Security and Quota tap will not
available.
You can convert FAT to NTFS file system from convert command
in windows xp.

My straight forward question is what is the size of the process and is it single process will create by operating system to complete the task of my application.??? Thanks in Advance.
