doesn't seem to work.

When referring to relative date 'values' using the < or > the value cannot be any of the keyword values related to dates (listed below). It must be a value using the format dd/mm/yy (or whatever format is specified in the "Region and Language" settings.

To find files older than x days, use the following:

datemodified:< dd/mm/yy

where dd/mm/yy is x days before the current (today's) date.


  • When entering dates use the date format which matches the "Control Panel" > "Region and Language" settings.

  • There is one exception to this, years should always be entered as 4 digits.
