Control Master File Table Zone Reservation

On NTFS-enabled XP systems, you can control the amount of space allocated to the Master File Table(MFT). The MFT contains reference entries to all the files on the system. This can get fragmented over time and affect system performance. Use this hack to allocate sufficient space for the MFT.

Navigate to:

HLM\System\CurrentControlSet\Control\FileSystem

Modify NtfsMftZoneReservation to a value between 1 and 4. For most users, a value of 3 is good enough. To be completely effective, this setting should be specified at the time the volume is formatted.
