Versão 1 powershell, get-childitem para procurar apenas em um diretório listado, nem todas as subpastas

Question

Eu tenho v1 de powershell nos meus servidores. Seria fácil se eu tivesse uma versão mais nova do PowerShell, mas isso não é uma opção para mim neste momento.

Eu tenho um script que verifica se um arquivo em uma pasta específica tem mais de 10 min e, se estiver, envie uma nota. O script funciona muito bem, se não houver subdiretórios ou apenas alguns diretórios, mas quanto mais o caminho demorar mais.

Eu também não posso simplesmente criar uma pasta separada para procurar, isso também não é uma opção.

Existe uma maneira de executar essa linha para que eu olhe apenas para arquivos e não para diretórios? Ah, e sim, eu corri sem o -recurse mas não funcionou.

function FileAge($path, $days, $hours, $mins)
{
    $files = @(get-childitem $path -include *.* -recurse | where {($_.psIsContainer -eq $false) -and ($_.LastWriteTime -lt (Get-Date).AddDays(-$days).AddHours(-$hours).AddMinutes(-$mins))})
    ...

Sem entrar em muitos detalhes, ele funciona se eu tiver o caminho c: \ temp .. demora cerca de 30 segundos, mas se eu mudar o caminho para c: \ demora 2 horas.

Linha de comando:

ps-run.cmd listf15.ps1

primeira execução ~ 33 GB / min (~ 30 min - 1Tb)

última execução ~ 125-250 GB / min (~ 8-4 min - 1Tb)

é lento ...

ps-run.cmd:

@IF "%time:~0,1%" GTR "0" SET current=%DATE:~-4%-%DATE:~3,2%-%DATE:~0,2%@%TIME:~0,2%.%TIME:~3,2%.%TIME:~6,2% 
@IF "%time:~0,1%" LSS "0" SET current=%DATE:~-4%-%DATE:~3,2%-%DATE:~0,2%@0%TIME:~1,1%.%TIME:~3,2%.%TIME:~6,2%
@echo %current%                                                                                              
powershell .\%* 9>&1 8>&1 7>&1 6>&1 5>&1 4>&1 3>&1 2>&1 0>&1 >> .\err%current%.txt
