使用PowerShell删除回收站中的旧文件

标签： powershell recycle-bin

好的，我有一个我在powershell中编写的脚本，它将删除回收站中的旧文件。我希望它删除回收站中超过2天前删除的所有文件。我对此做了很多研究，但没有找到合适的答案。

这就是我到目前为止（在线发现脚本，我不太了解PowerShell）：

$Path = 'C' + ':\$Recycle.Bin'
Get-ChildItem $Path -Force -Recurse -ErrorAction SilentlyContinue |
#Where-Object { $_.LastWriteTime -lt (Get-Date).AddDays(-3) } |
Remove-Item -Recurse -exclude *.ini -ErrorAction SilentlyContinue

它有一个例外，它检查文件参数＆＃34; LastWriteTime＆＃34;。如果用户在修改文件的同一天删除文件，那就太棒了。否则就失败了。

如何修改此代码，以便检查文件何时被删除，而不是在文件被写入时。

- 旁注，如果我从Microsoft Server 2008上的管理员帐户运行此脚本，它是否适用于所有用户回收站或只是我的？

答案：

对我有用的代码是：

$Shell = New-Object -ComObject Shell.Application
$Global:Recycler = $Shell.NameSpace(0xa)

foreach($item in $Recycler.Items())
{
    $DeletedDate = $Recycler.GetDetailsOf($item,2) -replace "\u200f|\u200e",""
    $dtDeletedDate = get-date $DeletedDate 
    If($dtDeletedDate -lt (Get-Date).AddDays(-3))
    {
        Remove-Item -Path $item.Path -Confirm:$false -Force -Recurse
    }#EndIF
}#EndForeach item

它对我来说很棒，但是还有2个问题......如何使用多个驱动器执行此操作？这适用于所有用户还是仅适用于我？

WMF 5包含新的“Clear-RecycleBin”cmdlet。

  

PS＆gt; Clear-RecycleBin -DriveLetter C：\

答案 1 :(得分：4)

这两行将清空所有文件回收站：

$Recycler = (New-Object -ComObject Shell.Application).NameSpace(0xa)
$Recycler.items() | foreach { rm $_.path -force -recurse }

这也可以作为任务调度程序的脚本。

答案 4 :(得分：0)

不得不对此进行一些研究，回收站包含两个文件，用于在win 10中的每个驱动器上删除的每个文件（在win 7文件中是这样的，所以这个脚本太多了，需要减少，特别是对于powershell 2.0，win 8未经测试），删除时创建的信息文件$ I（非常适合确定删除日期）和原始文件$ R，我发现com对象方法会忽略比我喜欢的更多文件但在上方有我感兴趣的信息关于原始文件被删除，所以经过一些探索我发现一个简单的获取内容的信息文件包括原始文件位置，清理后用一点正则表达式和想出了这个：

    [System.Runtime.InteropServices.DllImport("Shell32.dll")] 
    private static extern int SHChangeNotify(int eventId, int flags, IntPtr item1, IntPtr item2);
    public static void Refresh() {
        SHChangeNotify(0x8000000, 0x1000, IntPtr.Zero, IntPtr.Zero);    
    }
'@

# Set Safe within deleted days and get physical drive letters
$ignoreDeletedWithinDays = 2
$drives = (gwmi -Class Win32_LogicalDisk | ? {$_.drivetype -eq 3}).deviceid

# Process discovered drives
$drives | % {$drive = $_
    gci -Path ($drive+'\$Recycle.Bin\*\$I*') -Recurse -Force | ? {($_.LastWriteTime -lt [datetime]::Now.AddDays(-$ignoreDeletedWithinDays)) -and ($_.name -like "`$*.*")} | % {

        # Just a few calcs
        $infoFile         = $_
        $originalFile     = gi ($drive+"\`$Recycle.Bin\*\`$R$($infoFile.Name.Substring(2))") -Force
        $originalLocation = [regex]::match([string](gc $infoFile.FullName -Force -Encoding Unicode),($drive+'[^<>:"/|?*]+\.[\w\-_\+]+')).Value
        $deletedDate      = $infoFile.LastWriteTime
        $sid              = $infoFile.FullName.split('\') | ? {$_ -like "S-1-5*"}
        $user             = try{(gpv "HKLM:\Software\Microsoft\Windows NT\CurrentVersion\ProfileList\$($sid)" -Name ProfileImagePath).replace("$(gpv 'HKLM:\Software\Microsoft\Windows NT\CurrentVersion\ProfileList' -Name ProfilesDirectory)\",'')}catch{$Sid}

        #' Various info
        $originalLocation
