        $Unit='MB'
    }
    write-host $i.FullName  ' -- '  $FileSize  $Unit -fore green
}

获取文件夹内的文件数量

[System.IO.Directory]::GetFiles("d:\flutter", '*', 'AllDirectories').Count

或者

Get-ChildItem -Path "d:\flutter" -Force -Recurse -ErrorAction SilentlyContinue |
 Where-Object { $_.PSIsContainer -eq $false } |
 Measure-Object | 
 Select-Object -ExpandProperty Count
