Unlike typical backup programs that copy files, DrvImagerXP makes backups (image files) of NTFS and FAT32 drive partition structures (as well as floppy disks), for the Windows 2000/XP operating systems, by copying, byte-for-byte, the drive partition sectors. And when not using file compression, can do this very quickly, much faster than copying files.
