monitor a folder and trigger a command-line action when a file is created ?
At work we use Powershell to monitor folders.It can be used since Windows Vista (.NET and PowerShell is preinstalled) without any additional tools.
This script monitors a certain folder and writes a logfile. You can replace the action and do whatever you want e.g call an external tool
Example log file
11/23/2014 19:22:04, Created, D:\source\New Text Document.txt
11/23/2014 19:22:09, Changed, D:\source\New Text Document.txt
11/23/2014 19:22:09, Changed, D:\source\New Text Document.txt
11/23/2014 19:22:14, Deleted, D:\source\New Text Document.txt
StartMonitoring.ps1
### SET FOLDER TO WATCH + FILES TO WATCH + SUBFOLDERS YES/NO
$watcher = New-Object System.IO.FileSystemWatcher
$watcher.Path = "D:\source"
$watcher.Filter = "*.*"
$watcher.IncludeSubdirectories = $true
$watcher.EnableRaisingEvents = $true
### DEFINE ACTIONS AFTER AN EVENT IS DETECTED
$action = { $path = $Event.SourceEventArgs.FullPath
$changeType = $Event.SourceEventArgs.ChangeType
$logline = "$(Get-Date), $changeType, $path"
Add-content "D:\log.txt" -value $logline
}
### DECIDE WHICH EVENTS SHOULD BE WATCHED
Register-ObjectEvent $watcher "Created" -Action $action
Register-ObjectEvent $watcher "Changed" -Action $action
Register-ObjectEvent $watcher "Deleted" -Action $action
Register-ObjectEvent $watcher "Renamed" -Action $action
while ($true) {sleep 5}
How to use
[*]Create a new text file
[*]Copy & paste the above code
[*]Change the following settings to your own needs:
[*]folder to monitor: $watcher.Path = "D:\source"
[*]file filter to include only certain file types: $watcher.Filter = "*.*"
[*]include subdirectories yes/no: $watcher.IncludeSubdirectories = $true
[*]Save and rename it to StartMonitoring.ps1
[*]Start monitoring by Right click » Execute with PowerShell
To stop monitoring, it's enough to close your PowerShell window
