Configure file systems by using NTFS, FAT32, or FAT.
FAT File allocation table refers to a disk format, which is a
way of organizing the storage space on a hard disk. The table
organizes information about the files on the hard disk, representing
each one as a chain of numbers that identifies where each part of a
file is located. The operating system uses it to look up a file and
find which clusters that file is written to on the hard disk.
FAT16 Supports drives up to 2 gigabytes in size. Fat16 is the
most compatible file system, not only can all windows versions use
it but many other OS's also.
FAT32 Supports drives of up to 2 terabytes in size. FAT32
also reduces the cluster size on large drives, freeing up more
space.

NTFS4 New Technology File System
used with win NT 4 provides greater security than FAT, and
better disk compression. Support for large
hard disks, up to 2 terabytes and as drive size increases,
performance with NTFS doesn't degrade as it does with FAT.
NTFS5 Updated NTFS for windows
2000,NTFS The NTFS file system is the recommended file system for
use with Windows 2000. NTFS has all of the basic capabilities of
FAT, and it provides the following advantages over the FAT and FAT
32 file systems:
Better file security with encrypting file system (EFS)
Better disk compression.
Support for large hard disks, and as drive size increases,
performance with NTFS doesn't degrade as it does with FAT.
