我的服务器上有 Powershell v1。如果我有较新版本的 PowerShell，那会很容易，但目前对我来说这不是一个选择。

我有一个脚本，用于查看特定文件夹中的文件是否已超过 10 分钟，如果是，则发送通知。如果没有子目录或只有几个目录，该脚本效果很好，但目录越多，所需的时间就越长。

我也不能只创建一个单独的文件夹来查看，这也不是一个选择。

有没有办法可以运行此行，以便我只查看文件而不查看目录？哦，是的，我确实在没有 -recurse 的情况下运行了它，但它不起作用。

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))})
    ...

无需赘述，如果我有路径 c:\temp，它确实可以工作。大约需要 30 秒，但如果我将路径更改为 c:\，则需要 2 个小时。

命令行：

ps-run.cmd listf15.ps1

首次运行~33 GB/分钟（~30 分钟 - 1Tb）

上次运行~125-250 GB/分钟（~8-4 分钟 - 1Tb）

它很慢……

ps-运行.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%

列表f15.ps1：

$RunTime = [System.Diagnostics.Stopwatch]::StartNew()
$CurentTime=$(get-date)

Foreach ($file in $Files) {

$i++
}

write-host "Count : $i"

$CurentTime=$(get-date)

ac -Path $logfile -Va $ReportLine
ac -Path $logfile -Va "Count : $i"

write-host "End @ $CurentTime"
write-host "Total Run : $($RunTime.Elapsed.ToString())"

ac -Path $logfile -Va $CurentTime
ac -Path $logfile -Va "Total Run : $($RunTime.Elapsed.ToString())"

ac -Path $logfile -Va $ReportLine

输出，SystemDrive.txt：
