Unfortunately, this is not possible.

You can, however, use a simple Powershell script for this, such as:

Remove-Item C:\path\to\files\* -Recurse -Force -Include *.* -Verbose | Where-Object { $_.LastWriteTime -lt (Get-Date).AddMonths(-2) }

This will delete all files in C:\path\to\files\* which are older than 2 months.

Thanks,

I finally went with;

Try {

  $path = "C:\ImportTool\ErrorRows\Devices"

  $fileCount = (Get-ChildItem $path | Where-Object { !$_.PSIsContainer }).Count

    if ($fileCount -gt 20) {

      $filesToDelete = (Get-ChildItem $path | Where-Object { !$_.PSIsContainer } | Sort-Object LastWriteTime | Select-Object -First ($fileCount - 20))

      foreach ($file in $filesToDelete) {

       Remove-Item $file.FullName -Force

      }

    }  

  } 

  Catch {

    Write-Host "Cleanup didnt work"

  }
