使用PowerShell刪除回收站中的舊文件

Question

好的，我有一個我在powershell中編寫的腳本，它將刪除回收站中的舊文件。 我希望它刪除回收站中超過2天前刪除的所有文件。 我對此做了大量研究，但沒有找到合適的答案。

這是我到目前為止（在線發現腳本，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

它有一個例外，它檢查文件參數“LastWriteTime”。 如果用戶在修改文件的同一天刪除文件，那就太棒了。 否則它會失敗。

如何修改此代碼，以便檢查文件何時被刪除，而不是在寫入文件時。

- 旁注，如果我從Microsoft Server 2008上的管理員帳戶運行此腳本，它是否適用於所有用戶回收箱或僅我的？

回答：

對我有用的代碼是：

$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

它對我來說很棒，但是還有兩個問題......如何使用多個驅動器？ 這適用於所有用戶還是僅適用於我？

Answer 1

WMF 5包含新的“Clear-RecycleBin”cmdlet。

PS> Clear-RecycleBin -DriveLetter C：\\

Answer 2

這兩行將清空所有文件回收站：

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

Answer 4

這也可以作為任務調度程序的腳本。

Clear-RecycleBin -Force

Answer 5

不得不自己做一些研究，回收站包含兩個文件，用於win 10中每個驅動器上刪除的每個文件（在win 7文件中是這樣的，所以這個腳本太多了，需要減少，特別是對於powershell 2.0，win 8 untested），刪除時創建的信息文件$ I（非常適合確定刪除日期）和原始文件$ R，我發現com對象方法會忽略比我喜歡的更多文件但是在up side有信息我對刪除的原始文件感興趣，所以經過一些探索我發現一個簡單的獲取內容的信息文件包括原始文件位置，用一些正則表達式清理后，得出了這個：

# Refresh Desktop Ability
$definition = @'
    [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);    
    }
'@
Add-Type -MemberDefinition $definition -Namespace WinAPI -Name Explorer

# 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
        $deletedDate
        $user
        $sid
        $infoFile.Fullname
        ((gi $infoFile -force).length / 1mb).ToString('0.00MB')
        $originalFile.fullname
        ((gi $originalFile -force).length / 1mb).ToString('0.00MB')
        ""

        # Blow it all Away
        #ri $InfoFile -Recurse -Force -Confirm:$false -WhatIf
        #ri $OriginalFile -Recurse -Force -Confirm:$false- WhatIf
        # remove comment before two lines above and the '-WhatIf' statement to delete files
    }
}
