Question

我制作了这个小脚本，用于监视音乐文件夹中的新文件，并将它们移到相应的Artist文件夹中。如果该文件夹不存在，它将创建它，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也会触发脚本中的ObjectEvent，因此它开始变得愚蠢。是否可以更改脚本，使其仅在添加新文件时触发事件，而不在添加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

您可以重写操作以检查文件还是文件夹。 if((Get-ChildItem $Event.SourceEventArgs.FullPath -File))仅在项目为文件时获取。

###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
            if((Get-ChildItem $Event.SourceEventArgs.FullPath -File)){
                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 $action
while ($true) {
    sleep 2 
    Write-Host "Monitoring"
}

ArcSet非常近，他向我指出了正确的方向。这是我用的：

###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
                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"
}

使用powershell监视文件夹中的新文件，但忽略新文件夹
