Speaking of operating system, computer user would first be reminded of Windows XP like what stock reminds investor of Buffett. As another masterpiece after Windows 2000 released by Microsoft supporting FAT16, FAT 32 and NTFS file systems, Windows XP boasts better file management performance than early Windows operating systems. FAT, file system coming into existence with MS-DOS and other Windows operating systems, supports multiple operating systems but easily produce file fragments and waste disk space with poor security performance, for example, cluster size of FAT32 under Windows operating system must be smaller than 64KB, or disk space will not be correctly calculated. With the elapse of time and improvement of technology, FAT was gradually eliminated and a new file system by the name of NTFS came into emergence. NTFS is the standard file system for Windows NT, Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008Windows Vista and Windows 7 that has replaced FAT file system to be the most popular and functional partition format by making several great improvements such as supporting metadata, utilizing high-level data structure so as to enhance partition performance, reliability, disk space utilization and providing additional expended functions like ACL and file system blog. Although NTFS has fantastic file management performance, user still needs third-party partition magic software to help manage disk partitions under Windows operating systems. MiniTool Partition Wizard is the most outstanding one among partition magic.
