What is NTFS?
A file system is a method of storing and organizing computer files and the #data they contain. It also maintains the physical location of the files so that you can easily find and access the files in the future. Windows Server 2008 supports FAT16, FAT32, and NTFS file systems on hard drives.
After you partition a disk, you then need to format the disk. You can format the disk as FAT16, FAT32, or NTFS. Of these, NTFS is the preferred file system for today’s operating systems.
FAT16, sometimes referred to generically as File Allocation Table (FAT), is a simple file system that uses minimal memory and has been used with DOS. Originally it supported the 8.3 naming scheme, which allowed up to an eight-character filename and three-character filename extension. Later, it was revised to support longer filenames. Unfortunately, FAT volumes can
only support up to 2 GB.
FAT32 was released with the second major release of Windows 95. Although this file system can support larger drives, today’s Windows supports volumes up to 32 GB. It also supports long filenames.
Today, NTFS is the preferred file system because it supports both volumes up to 16 exabytes and long filenames. In addition, NTFS is more fault tolerant than previous file systems used in Windows because it is a journaling file system. A journaling file system makes sure that a transaction is written to disk properly before being recognized. Finally, NTFS offers better
security through permissions and encryption.
