Although Windows 95 and all subsequent
versions of Windows more or less eliminated this restriction,
an eight-dot-three version of a filename is generated with each file you
create to maintain compatibility with older applications. For example,
the file A letter to Mom.wpd could also be referenced as alette~1.wpd.
If you don??™t use older 16-bit programs, you can disable Vista??™s creation
of these 8.3 aliases by changing this value to 1 (the default is zero).
Hard Disk | 257
Performance
NtfsDisableLastAccessUpdate
Values: 0 = enabled (default), 1 = disabled.
Windows keeps a record of the time and date every file and folder on
your hard disk was created, as well as when it was last modified and last
accessed. You can stop Windows from updating the ???last accessed??? date
for folders every time they??™re opened by changing the value to 1 (the
default is zero), which may improve drive performance. This setting has
no effect on files.
NtfsMftZoneReservation
Values: 1 = small (default), 2 = medium, 3 = large, 4 = maximum.
The core of the NTFS filesystem is the master file table (MFT), a comprehensive
index of every file on the disk (including the MFT itself).
Since disk defragmenters can??™t defragment the MFT (also known as
$mft), Windows reserves a certain amount of extra space for it to grow,
in an effort to reduce its eventual fragmentation. The more fragmented
the MFT gets, the more it will hamper overall disk performance.
