Question

我想要一个选中的文件夹，但是在此之前，我需要检查该文件夹中是否存在某个文件。如果可以，我需要执行一些操作，如果不需要，请执行其他操作。

我需要每次检查该文件是否存在。因此，这是一个正在运行的过程。我不能执行一次。

预先感谢

到目前为止，我有这个：

$root= [Environment]::GetFolderPath("Desktop")
$foldertmp = "$root\UNB\TMP\"
$filter = 'FACT_TEMPORAL.TXT'                             # <-- set this according to your requirements
$PDFDestination = "$root\UNB\NO_PROCESADO\"
#C:\Users\JuanMa\Desktop\UNB\TMP

Write-Host "EL ROOT ES $root" -fore white

$fsw = New-Object IO.FileSystemWatcher $foldertmp, $filter -Property @{
 IncludeSubdirectories = $true              # <-- set this according to your requirements
 NotifyFilter = [IO.NotifyFilters]'FileName, LastWrite'
}

$onCreated = Register-ObjectEvent $fsw Created -SourceIdentifier FileCreated -Action {
 $path = $Event.SourceEventArgs.FullPath
 $name = $Event.SourceEventArgs.Name
 $changeType = $Event.SourceEventArgs.ChangeType
 $timeStamp = $Event.TimeGenerated

 Write-Host "The file '$name' at '$path'was $changeType at $timeStamp" -fore white

function comprobar()

    if(!(Test-Path 'C:\Users\JuanMa\Desktop\UNB\TMP\FACT_TEMPORAL.TXT')){

    Get-Printer -Name "UNBILLING" | select Name, PrinterStatus, JobCount, DriverName 
    }

    if((Test-Path 'C:\Users\JuanMa\Desktop\UNB\TMP\FACT_TEMPORAL.TXT')){
    Write-Host "Archivo existe. Error" -fore white
    Get-Printer -Name "UNBILLING" | select Name, PrinterStatus, JobCount, DriverName 
    limpia
    renombra_noprocesado
    borrar
    }

}


function limpia() 
{
    $regex = [System.Text.RegularExpressions.Regex]
    write-host "FUNCION LIMPIA ARCHIVO TXT" -fore white 
    $a = get-content $root\UNB\TMP\FACT_TEMPORAL.txt | 
        Foreach-Object { $regex::Replace($_, '^[.! pÿ>i@]{1,}', '') } |
