folder lastaccesstime

(before | after) datetime
between datetime and datetime

Purpose

Warns when the specified folder's most recently accessed files have a last access time which is not before or after a specified date (and optionally time), or not within a specified timespan.

Windows allows disabling last access time on NTFS folders

NTFS folders don't necessarily have an accurate last access time because this metadata can be disabled in order to prevent a lot of writing and, ostensibly, boost performance. When Windows 2000 was current (circa March 2010), Microsoft wrote:

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 directories list faster.

Use the following fsutil commands from an administrative shell:
To check the current setting: fsutil behavior query disablelastaccess
To enable Last access time update: fsutil behavior set disablelastaccess 0
To disable Last access time update: fsutil behavior set disablelastaccess 1

Or set relevant group policy to set a new default, then restart the computer.

Purpose

Warns when the specified folder's last access time is not before or after a specified date (and optionally time), or not within a specified timespan.

Notes

This requirement may be repeated in the same section.

“Before” warns when a specified folder's last access time is on or after a specified date/time.
“After” warns when a specified folder's last access time is on or before a specified date/time.
“Between” warns when a specified folder's last access time is not within a specified pair of dates/times.
All times and dates are (by default) in the timezone of the system on which Martinet runs.
