Data type Range Default value
REG_DWORD 0 | 1 0


Determines whether NTFS updates the last-access time stamp on each directory when it lists the directories on an NTFS volume.

This entry is designed to prevent the NTFS log buffer in physical memory from becoming filled with time stamp update records. If you have an NTFS volume with a very large number of directories (in excess of 70,000), and Windows 2000 does not respond quickly to dir commands, adding this entry to the registry might make directory listings faster.

Value Meaning
0 When listing directories, NTFS updates the last-access time stamp on each directory it detects and writes a record to the NTFS log noting each time change.
1 When listing directories, NTFS does not update the last-access time stamp and does not write time stamp update records to the NTFS log.

Note Image Note

Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program, such as Group Policy, that edits the registry.
