If NTFS updates other file attributes such as Last Modify Time, and a Last Access Time update is pending, NTFS updates Last Access Time with the other updates without additional performance impact. One hour is the maximum amount of time that NTFS can defer updating Last Access Time on disk. NTFS returns the correct value on queries because the accurate value is stored in memory. This parameter updates the HKLM\SYSTEM\CurrentControlSet\Control\FileSystem\NtfsDisableLastAccessUpdate registry key.įile-based Last Access Time queries are accurate even if all on-disk values aren't current.
Disabling the Last Access Time feature improves the speed of file and directory access. The disablelastaccess parameter reduces the impact of logging updates to the Last Access Time stamp on files and directories. The allowextchar parameter updates the HKLM\SYSTEM\CurrentControlSet\Control\FileSystem\NtfsAllowExtendedCharacterIn8dot3Name registry key. This parameter updates the HKLM\SYSTEM\CurrentControlSet\Control\FileSystem\NtfsDisable8dot3NameCreation registry key. When NTFS creates files in a directory, it must look up the 8.3 character-length file names that are associated with the long file names. When disable8dot3 is set to 0, every time you create a file with a long file name, NTFS creates a second file entry that has an 8.3 character-length file name. If the average file size on the volume is 1 KB or less, it can be beneficial to set the mftzone value to 4. If the average file size on the volume is 2 KB or less, it can be beneficial to set the mftzone value to 2. The MFT Zone is a reserved area that enables the master file table (MFT) to expand as needed to prevent MFT fragmentation.
