使用powershell监视文件夹中的新文件，但忽略新文件夹

我制作了一个小脚本，它监视我的音乐文件夹中的新文件，并将它们移动到相应的艺术家文件夹中。如果该文件夹不存在，它将创建该文件夹，然后将mp3/flac/m4a文件移动到新创建的文件夹中。唯一的问题是，当它创建这个新文件夹时，它也会在脚本中触发ObjectEvent，因此它开始表现出愚蠢的行为。是否可以更改脚本，使其仅在添加新文件而不是新文件夹时触发事件

###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
            $logline = "$(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 $action
while ($true) {
sleep 2 
Write-Host "Monitoring"
}

您可以重写操作以检查文件或文件夹是否正确<代码>如果（（Get ChildItem$Event.SourceEventArgs.FullPath-File））仅当项目是文件时才获取该项目

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

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

$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
            if((Get-ChildItem $Event.SourceEventArgs.FullPath -File)){
                write-host "FILE"
                $changeType = $Event.SourceEventArgs.ChangeType
                $logline = "$(Get-Date), $changeType, $path"

ArcSet离我很近，他给我指出了正确的方向。以下是我使用的：

###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

                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

                }
          }    
### 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

查看

.NotifyFilter

属性。我认为这是你需要的，但还没有测试过。从这里得到的。。。FileSystemWatcher类（System.IO）| Microsoft文档-我看到了.Filter属性&它似乎只适用于一种类型的文件。似乎我无法将其过滤到.flac/.mp3/.m4a/.wav等。NotifyFilter属性看起来很有趣，但只需重写操作以检查文件夹…尝试了。似乎不起作用。编辑脚本以写入主机$path，您将看到，当它创建文件夹时，它收到了事件，并且仍然认为它是一个文件@ark。您正在使用新的powershell实例，因为我没有看到您注销事件。如果您使用同一个powershell实例，那么它只会注册越来越多的事件，直到您关闭powershell。
