copy in powershell does not work as excpected - powershell

Question

I have the following powershell script that not quite work as I thought it would. I want to copy the new created file in the source folder ($folder) to my destination folder ($DestFolder), but no file is copied. Anyone see what could be wrong?
$SourceFolder = 'd:\temp\' # Enter the root path you want to monitor.
$folder = 'd:\temp' # Enter the root path you want to monitor.
$Destfolder = 'd:\temp2\' # Enter the root path you want to monitor.
$global:MySourceFolder = 'd:\temp\' # Enter the root path you want to monitor.
$global:MyDestfolder = 'd:\temp2\' # Enter the root path you want to monitor.
$filter = '*.*' # You can enter a wildcard filter here.
# In the following line, you can change 'IncludeSubdirectories to $true if required.
$fsw = New-Object IO.FileSystemWatcher $folder, $filter -Property #{IncludeSubdirectories = $false;NotifyFilter = [IO.NotifyFilters]'FileName, LastWrite'}
Register-ObjectEvent $fsw Created -SourceIdentifier FileCreated -Action {
$name = $Event.SourceEventArgs.Name
$changeType = $Event.SourceEventArgs.ChangeType
$timeStamp = $Event.TimeGenerated
#Write-Host "The file '$name' was $changeType at $timeStamp" -fore green
Write-Host "path : $MyDestfolder$name" -fore green
Copy-Item (Join-Path $MySourceFolder $name) ($Destfolder)
Out-File -FilePath d:\temp\filechange\outlog.txt -Append -InputObject "The file '$name' was $changeType at $timeStamp"}

I believe it is working as intended. If the copy actually is part of the action, try moving that line inside the action script block.
The variable $name is empty outside the action scriptblock since the ObjectEvent has its own scope. If you need to access this variable from outside the Action scriptblock you could declare the variable using $global:name.
The following really should work (replace with this but save a copy of your code so you've got a backup first)
$folder = 'd:\temp'
$Destfolder = 'd:\temp2'
$filter = '*.*'
$fsw = New-Object IO.FileSystemWatcher $folder, $filter -Property #{
IncludeSubdirectories = $false
NotifyFilter = [IO.NotifyFilters]'FileName, LastWrite'
}
Register-ObjectEvent $fsw Created -SourceIdentifier FileCreated -Action {
$name = $Event.SourceEventArgs.Name
$changeType = $Event.SourceEventArgs.ChangeType
$timeStamp = $Event.TimeGenerated
Write-Host "The file '$name' was $changeType at $timeStamp" -fore green
Copy-Item -Path (Join-Path $folder $name) -Destination $Destfolder
Out-File -FilePath "d:\temp\filechange\outlog.txt" -Append -InputObject "The file '$name' was $changeType at $timeStamp"
}
