Thanks opc,

that is the article I used to dev with and then I tried all different options.

i ORIGINALLY USED

SELECT *

FROM __InstanceCreationEvent WITHIN 1800

WHERE TargetInstance ISA 'CIM_DataFile'

AND TargetInstance.Drive = 'T:'

AND TargetInstance.Path = '\\Business Intelligence\\SAP Stock and Distribution File Dump\\'

AND TargetInstance.FileName LIKE '%Trigger%'

AND TargetInstance.Extension = 'txt'

BUT GOT AN ERROR

[WMI Event Watcher Task] Error: An error occurred with the following error message: "Invalid parameter ".

any ideas?
