powershell - 使用 powershell 检索用户配置文件的大小

Question

我正在尝试检索 Windows 机器中配置文件的确切大小。

下面是我的代码和O/P

$profiles = Get-ChildItem C:\Users | ?{Test-path C:\Users\$_\NTUSER.DAT} | Select -ExpandProperty Name
  foreach($profile in $profiles)
    {
    $largeprofile = Get-ChildItem C:\Users\$profile  -recurse | Measure-Object -Sum length | Select -ExpandProperty Sum
    $largeprofile = [math]::Round(($largeprofile/1MB),2) + "MB"
    if($largeprofile -lt 20){Continue}
    $object = New-Object -TypeName PSObject
    $object | Add-Member -MemberType NoteProperty -Name Name -Value $profile
    $object | Add-Member -MemberType NoteProperty -Name "Size(MB)" -Value $largeprofile
    ($object | fl | Out-String).Trim();Write-Output "`n"
    }

O/P

Name : admin

Size(MB) : 34.62

但是文件夹的确切大小为 181MB，powershell 无法读取父文件夹内的所有文件夹和文件，我如何才能获得文件夹属性中显示的确切大小。

注意:对于配置文件文件夹以外的文件夹，o/p 是正确的。

递归目录时，您必须将参数-Force 添加到Get-ChildItem。来自文档 Get-ChildItem -Force 参数:

Allows the cmdlet to get items that cannot otherwise not be accessed by the user, such as hidden or system files.

此外，您需要添加 -ErrorAction SilentlyContinue，这样您就不会被 Access Denied 错误淹没。这些更改使您的代码看起来像这样:

$profiles = Get-ChildItem C:\Users | ?{Test-path C:\Users\$_\NTUSER.DAT} | Select -ExpandProperty Name
  foreach($profile in $profiles)
    {
    $largeprofile = Get-ChildItem C:\Users\$profile -Recurse -Force -ErrorAction SilentlyContinue | Measure-Object -Sum length | Select -ExpandProperty Sum
    $largeprofile = [math]::Round(($largeprofile/1MB),2) + "MB"
    if($largeprofile -lt 20){Continue}
    $object = New-Object -TypeName PSObject
    $object | Add-Member -MemberType NoteProperty -Name Name -Value $profile
    $object | Add-Member -MemberType NoteProperty -Name "Size(MB)" -Value $largeprofile
    ($object | fl | Out-String).Trim();Write-Output "`n"
    }
