The NTFS file system

The exFAT file system

The FAT file system

Files stored to a FAT partition cannot exceed 4GB.FAT partitions need to be defragmented often to maintain reasonable performance. FAT is generally only used for devices with small capacity where portability between operating systems is important. When choosing a file system for a hard disk, FAT is not recommend unless you are using an older version of Windows.

The exFAT is also compatible with many media devices such as TVs and portable media players.

exFAT has the following properties:

· exFAT partitions can extend up extremely large disc sizes. 512 TiB is the recommended maximum.

· Files up to 16 EiB can be stored on an exFAT partition.

· exFAT is not compatible with linux/Unix.

· exFAT cannot pre-allocate disk space.

NTFS (New Technology File System) is a modern, well-formed file system that is most commonly used by Windows Vista, 7 & 8. It has feature-rich, yet simple organization that allows it to be used on very large volumes.

NTFS has the following properties:

· NTFS partitions can extend up to 16EB (about 16 million TB).

· Files stored to NTFS partitions can be as large as the partition.

· NTFS partitions occasionally become fragmentented and should be defragmented every one to two months.

It is recommended that NTFS be used on all media whose use is primarily with modern Windows systems. It should not be used for devices which need to be written to by Mac OS X systems or on media that is used in devices which are not compatible with NTFS.

20. Customizing Windows.

There are many ways you can customize Windows to make your computer more accessible.

Accessibility features have been built in to Windows since the introduction of Windows 95. These features are useful for individuals who have difficulty typing or using a mouse, have moderately impaired vision, or are deaf or hard-of-hearing. The features can be installed during Setup, or you can add them later from your Windows installation disks.

• Some of the accessibility features in Windows can be added to earlier versions of those products, and to MS-DOS, through Access Packs. You can download these files from Microsoft.

• You also can use Control Panel and other built-in features to adjust the appearance and behavior of Windows to suit varying vision and motor abilities. These include adjusting colors and sizes, sound volume, and the behavior of the mouse and keyboard.

• The Accessibility Wizard helps you configure Windows for your vision, hearing, and mobility needs.

• Dvorak keyboard layouts make the most frequently typed characters more accessible if you have difficulty using the standard keyboard layout. There are three Dvorak layouts: one if you are a two-handed user, one if you type with your left hand only, and one if you type with your right hand only. You do not need to purchase any special equipment to use these features.

The specific features available, and whether they are built-in or must be obtained separately, depend on the operating system you are using
