Контролируйте папку для нового файла, используя powershell, но игнорируйте новые папки

Question

У меня есть этот небольшой скрипт, который я проверяю на наличие новых файлов в моей музыкальной папке и перемещает их в соответствующую папку артистов. Если эта папка не существует, она создает ее, а затем перемещает файл mp3 / flac / m4a во вновь созданную папку. Единственная проблема заключается в том, что когда он создает эту новую папку, которая также запускает ObjectEvent в сценарии, так что он начинает действовать глупо. Можно ли изменить скрипт так, чтобы он вызывал событие только при добавлении новых файлов, а не новых папок?

###Load taglib
$TagLib = "F:\Music-10-12-2016\Scripts\taglib-sharp.dll"

#Load it into Powershell
[system.reflection.assembly]::loadfile($TagLib)

### SET FOLDER TO WATCH + FILES TO WATCH + SUBFOLDERS YES/NO
$watcher = New-Object System.IO.FileSystemWatcher
$watcher.Path = "F:\Music-10-12-2016\Leak"
$watcher.Filter = "*.*"
$watcher.IncludeSubdirectories = $false
$watcher.EnableRaisingEvents = $true  

### DEFINE ACTIONS AFTER AN EVENT IS DETECTED
$action = { Write-Host "Recieved Event"
            $path = $Event.SourceEventArgs.FullPath
            $changeType = $Event.SourceEventArgs.ChangeType

ArcSet был очень близко, и он указал мне правильное направление. Вот что я использовал:

###Load taglib
$TagLib = "F:\Music-10-12-2016\Scripts\taglib-sharp.dll"

#Load it into Powershell

[system.reflection.assembly]::loadfile($TagLib)

### SET FOLDER TO WATCH + FILES TO WATCH + SUBFOLDERS YES/NO
$watcher = New-Object System.IO.FileSystemWatcher
$watcher.Path = "F:\Music-10-12-2016\Leak"
$watcher.Filter = "*.*"
$watcher.IncludeSubdirectories = $false
$watcher.EnableRaisingEvents = $true  

### DEFINE ACTIONS AFTER AN EVENT IS DETECTED
$action = { Write-Host "Received Event"
            $path = $Event.SourceEventArgs.FullPath
            Write-Host $path
            if((Test-Path -Path $path -PathType Leaf)){ 
                Write-Host "FILE"
                $changeType = $Event.SourceEventArgs.ChangeType
                $logline = "$(Get-Date), $changeType, $path"
                $media = [TagLib.File]::Create(($path))
                $artists = [string]$media.Tag.Artists
                Write-Host $artists
                Write-Host $logline
                Write-Host $path
                Add-content "F:\Music-10-12-2016\Scripts\log.txt" -value $logline
                Add-content "F:\Music-10-12-2016\Scripts\log.txt" -value $artists
                if(!(Test-Path -Path "F:\Music-10-12-2016\Leak\$artists" )){
                    New-Item -ItemType directory -Path "F:\Music-10-12-2016\Leak\$artists"
                    Write-Host "New folder created"
                    Start-Sleep -s 2
                }
                Move-Item -Path "$path" -Destination "F:\Music-10-12-2016\Leak\$artists"
                Add-content "F:\Music-10-12-2016\Scripts\log.txt" -value "moved"
                }
          }    
### 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 2 
Write-Host "Monitoring"
}

Вы можете переписать действие, чтобы проверить, есть ли файл или папка. if((Get-ChildItem $Event.SourceEventArgs.FullPath -File)) Получает элемент, только если это файл.
