else, as defragmentation will run automatically after the analysis.

NTFS Compared with FAT
Hard disks can either use the NTFS file system, as set in current Windows versions as preference, or the old
FAT system as supported by the first Windows versions. Analysis of drives before defragmentation is
substantially faster on NTFS drives. For FAT systems, users must wait considerably longer and can take the
popular coffee break. This is just one of several reasons why the old FAT system should be converted to the
modern NTFS system.
The NTFS file system (NTFS = New Technology File System) is the file system from Windows NT and its
successors (e.g. Windows 2000, Windows XP, Windows Vista) right up to Windows 7. It offers an intelligently
devised access protection to file levels, allows flexible management of privileges, accommodates file sizes
above 4 GB, offers automatic error correction of the file system and can utilize the storage space of today's
standard hard disk sizes in a considerably more efficient manner.
If your hard disks still use the FAT file system, you can carry out a very simple conversion.
Although conversion is considered very secure, you should make a backup of your saved data before
attempting this.
Click the Windows Start icon to open All Programs, go to Accessories and click Command Prompt. If you
enter CONVERT.EXE C:/FS:NTFS in the command line, conversion will start.
Replace C: with another drive letter to convert a different partition. If the system partition is changed, the
computer will need to be restarted. In this case, follow the instructions on your screen.
