Multi-Path FileWatcher

#By BigTeddy 05 September 2011

#Modified by Mohamed Said "MohamedSaid82"

#This script uses the .NET FileSystemWatcher class to monitor file events in folder(s).
#The advantage of this method over using WMI eventing is that this can monitor sub-folders.
#The -Action parameter can contain any valid Powershell commands.  I have just included two for example.
#The script can be set to a wildcard filter, and IncludeSubdirectories can be changed to $true.
#You need not subscribe to all three types of event.  All three are shown for example.
# Version 1.1

# SMTP Server information

$SMTPServer = "mail.test.com"
$SMTPPort = "25"
$username = "Test1@test.com"
$password = "abc_123" | ConvertTo-SecureString -AsPlainText -Force
$cred = New-Object -typename System.Management.Automation.PSCredential -argumentlist $username, $password
$From = "fsrm@Test.Com"

# for every change for every monitored path the SourceIdentifier will change .

$i=0

# list of paths of the monitored folders . this path sould exist on your computer

$paths = Get-Content "C:\Scripts\Folder_monitored_paths.txt";

# list of users to send email to upon file or folder change . this path sould exist on your computer

$users = Get-Content "C:\Scripts\users.txt";



foreach ($path in $paths)

{

$filter = '*.*'  # You can enter a wildcard filter here.

# In the following line, you can change 'IncludeSubdirectories to $false if required to disable subfolder monitoring.

#  $fsw  : file system watcher variable can be either : option 1 to monitor only files or option 2 to monitor files and folders

# option 1 : $fsw = New-Object IO.FileSystemWatcher $path, $filter -Property @{IncludeSubdirectories = $tru;NotifyFilter = [IO.NotifyFilters]'FileName, LastWrite'}

# option 2 : $fsw = New-Object IO.FileSystemWatcher $path -Property @{IncludeSubdirectories = $true}

$fsw = New-Object IO.FileSystemWatcher $path -Property @{IncludeSubdirectories = $true}

# Here, all four events are registerd.  You need only subscribe to events that you need:

Register-ObjectEvent $fsw Created -SourceIdentifier "$i+folderCreated" -Action {

$name = $Event.SourceEventArgs.Name
$changeType = $Event.SourceEventArgs.ChangeType
$fpath = $Event.SourceEventArgs.FullPath
$timeStamp = $Event.TimeGenerated

# for tesing purpose , you can enable the following command to see the changes in an interactive console.

#Write-Host "The folder "$Event.SourceEventArgs.FullPath" was $changeType at $timeStamp" -fore green

#the follwing will log changes to a log file.

Out-File -FilePath c:\log\outlog.txt -Append -InputObject "The folder $fpath was $changeType at $timeStamp"

# the following for loop will send changes to every user lised in the $users variable indicationg the change that has happened.
