this script is for monitoring folder for create, delete or modified text files

sComputer = "."
sDrive = split(sPath,":")(0)
sFolders1 = split(sPath,":")(1)
sFolders = REPLACE(sFolders1, "\", "\\") & "\\"
Set objWMIService = GetObject("winmgmts:\\" & sComputer & "\root\cimv2")
Set colMonitoredEvents = objWMIService.ExecNotificationQuery _
("SELECT * FROM __InstanceOperationEvent WITHIN 1 WHERE " _
& "TargetInstance ISA 'CIM_DataFile' AND " _
& "TargetInstance.Drive='" & sDrive & "' AND " _
& "TargetInstance.Path='" & sFolders & "' AND " _
& "TargetInstance.Extension = 'txt' ")
Wscript.Echo vbCrlf & Now & vbTab & _
"Begin Monitoring for a Folder " & sDrive & ":" & sFolders1 & " Change Event..." & vbCrlf
Do
Set objLatestEvent = colMonitoredEvents.NextEvent
Select Case objLatestEvent.Path_.Class
Case "__InstanceCreationEvent"
WScript.Echo Now & vbTab & objLatestEvent.TargetInstance.FileName & "." & objLatestEvent.TargetInstance.Extension _
& " was created" & vbCrlf
Case "__InstanceDeletionEvent"
WScript.Echo Now & vbTab & objLatestEvent.TargetInstance.FileName & "." & objLatestEvent.TargetInstance.Extension _
& " was deleted" & vbCrlf
Case "__InstanceModificationEvent"
If objLatestEvent.TargetInstance.LastModified <> _
objLatestEvent.PreviousInstance.LastModified then
WScript.Echo Now & vbTab & objLatestEvent.TargetInstance.FileName & "." & objLatestEvent.TargetInstance.Extension _
& " was modified" & vbCrlf
End If
End Select
Loop
Set objWMIService = nothing
Set colMonitoredEvents = nothing
Set objLatestEvent = nothing
This script is run perfect when i write
sPath = "\\ComputerName\C$\scripts\test"
insted of
sPath = "C:\scripts\test"

If you google for "WMI TargetInstance.Drive", you'll see that the drive letter needs a colon. A query like
SELECT * FROM __InstanceOperationEvent WITHIN 1 WHERE TargetInstance ISA 'CIM_DataFile' AND TargetInstance.Drive='E:' AND TargetInstance.Path='\\trials\\SoTrials\\answers\\10041057\\data\\' AND TargetInstance.Extension = 'txt'
works as expected.
