"A","C",&"D"

I might just go "A" & "D"
The short names is convenient and not, "C" goes both ways

Correct Answers: A, C and D

A. Correct: NTFS tags each folder with the last access date and time in an NTFS partition whenever the folder structure is traversed. Traversing large disk with large folder structures is slowed by this date-and-time stamping process.

B. Incorrect: Creation of long filenames (LFNs) is automatic and cannot be disabled in NTFS.

C. Correct: For compatibility with MS-DOS or Windows 3.x applications that are unaware of LFNs, FAT, FAT32, and NTFS generate short filenames in 8.3 format when a file is created. Generating short filenames contributes to file system overhead.

D. Correct: NTFS uses the MFT as a file index. File properties including location information and entire files, if the files are small, are stored in the MFT. The MFT stores at least one entry for every file on an NTFS partition. As files are added to a partition, the MFT grows. Because the MFT is a file itself, it is susceptible to fragmentation. Exessive fragmentation in files impacts performance. The standard disk defragmenter included in Windows 2000 does not defragment the MFT. Therefore, to avoid fragmentation in the MFT, NTFS reserves space for it. The default space reservation is adequate for relatively small partitions that will not contain to many files.

Hi,

Thanks for the informative answers to this question. I am wondering if you or someone can explain or point to a reference on the web that shows one how to do these tasks. thanks.

A. To disable the last access update on NTFS partitions, add the NtfDisableLastAccessUpdate value name with a REG_WORD data type and a value of 1 to the HKEY_LOCAL_MACHINE\SYSTEM\Curr
entControlSet\Control\FileSyst
em key.

C. To disable the generation of 8.3 filenames on NTFS partitions, change the value of the NtfsDisable8dot3NameCreation registry entry from 0 to 1. This entry is located in the HKEY_LOCAL_MACHINE\SYSTEM\Curr
entControlSet\Control\FileSyst
em key. Files that already have both long and short filenames are unaffected by this change.

D. To increase contiguous space allocation for larger partitions that will contain many files, add the NtfsMftZoneReservation value name with a REG_WORD data type and a value of 2, 3, or 4 to the HKEY_LOCAL_MACHINE\SYSTEM\Curr
entControlSet\Control\FileSyst
em key. The larger the value of this registry entry, the more space that is allocated.
