monitor last modified time for a folder using batch file - batch-file

Question

I have a folder on my workstation where files are added every minute.
I have to monitor this folder every now and then, to see if new files are being added.
In case there is no new file in this folder for say 5 min, we perform an action.
Can we use batch file for this purpose in such a way that if there is no new file added for last 5 min, an alert /pop up apears on window screen.
Also I m new to Batch .Please let me know the steps

Answer 1

It seems unlikely that you are going to accomplish what you want to do with purely a batch file.
However, you can do this in a relatively simple/small VB Script, that doesn't require any additional installation on the system.
'-------------------------------------------------------------
' Monitors a folder for new files and warns if they
' are not being created within a certain time period.
'-------------------------------------------------------------
Dim intMinutes: intMinutes = 5 ' minute threshold for warning of no new files
Dim strDrive: strDrive = "c:" ' drive to monitor
Dim strPath: strPath = "\\temp\\" ' path to monitor. remember to double slashes
Dim intTimer: intTimer = "2"
Dim strComputer: strComputer = "."
Dim objWMIService: Set objWMIService = GetObject( "winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2" )
Dim strQuery: strQuery = "Select * From __InstanceOperationEvent" & " Within " & intTimer & " Where Targetinstance Isa 'CIM_DataFile'" & " And TargetInstance.Drive='" & strDrive & "'" & " And TargetInstance.Path='" & strPath & "'"
Dim colEvents: Set colEvents = objWMIService. ExecNotificationQuery (strQuery)
Dim LastNew: LastNew = Now
WScript.Echo "Monitoring new file creation... Press [Ctrl]-[C] to exit"
Do
Set objEvent = colEvents.NextEvent()
Set objTargetInst = objEvent.TargetInstance
Select Case objEvent.Path_.Class
Case "__InstanceCreationEvent"
LastNew = Now
End Select
if DateDiff("n",LastNew,Now) >= intMinutes then
' put whatever actions you want in here... the following two lines are for demo purposes only
msgbox "The last new file was " & DateDiff("n",LastNew,Now) & " minute ago!",0,"No New Files"
exit do
end if
Loop
Execute this in WScript to make it not visible or CScript to show the console window.
Replace the code inside the IF block to do what you need done (notify you of the issue).
