Question

我尝试使用Powershell v5.1压缩文件夹，但有些文件被其他进程使用，PS无法强制或忽略它们。

Get-ChildItem "C:\folder" | Compress-Archive -DestinationPath "C:\file.zip"

还使用-Force和-ErrorAction Ignore,Continue,SilentlyContinue进行了测试，但每次出现这样的错误时：

ZipArchiveHelper : The process cannot access the file 'C:\folder\filexyz' be cause it is being used by another process.
At C:\Windows\system32\WindowsPowerShell\v1.0\Modules\Microsoft.PowerShell.Archive\Microsoft.PowerShell.Archive.psm1:69

Answer 1

由于其他进程使用的文件仍然可以读取，我认为问题是权限不足。

尝试以管理员身份启动PowerShell（搜索PowerShell - ＆gt;右键单击 - ＆gt;以管理员身份运行）。

Answer 2

以下情况例外：当Exception calling ".ctor" with "1" argument(s): "Stream was not readable."与Compress-Archive一起使用多个文件并且一个或多个打开时发生。

您可以在将文件传送到Compress-Archive之前检查文件是否未锁定。

$items = Get-ChildItem -Path $path
[System.Collections.ArrayList]$itemsToCompress = @()
[System.Collections.ArrayList]$itemsToNotCompress = @()

foreach ($item in $items){
    Try {
        # Checking File Mode and Access
        $FileStream = [System.IO.File]::Open($item.FullName,'Open','Read')
        if ($null -ne $FileStream){
            $FileStream.Close()
            $FileStream.Dispose()
            $itemsToCompress += $item
        }
    }
    Catch {
        $itemsToNotCompress += $item
    }
}

$itemsToCompress | Compress-Archive -DestinationPath $archivefile -ErrorAction SilentlyContinue

Answer 3

您可以检查$ Error对象。如果在compress调用之后填充了它，则发生错误，您可以采取适当的措施。

$error.clear()
Get-ChildItem "C:\folder" | Compress-Archive -DestinationPath "C:\file.zip"
if ($error[0] -ne $null) {
    # Take appropriate action here
}
