 FAT32 was introduced with MS-DOS 7.1 / Windows 95 OSR2 in 1996, although reformatting was needed to use it, and DriveSpace 3 (the version that came with Windows 95 OSR2 and Windows 98) never supported it.Windows 98 introduced a utility to convert existing hard disks from FAT16 to FAT32 without loss of data.In the Windows NT line, native support for FAT32 arrived in Windows 2000.
