Question

我正在使用一个脚本将下载文件夹中的所有zip解压缩到桌面上的目录中。我可以正常使用它，但是尝试过一个.zip文件，这给我带来了麻烦。

当尝试ExtractToDirectory时，它返回有2个参数，并且“提取到Zip条目将导致文件超出指定的目标目录”，我能够使用WinZip以及文件浏览器的Extract All来解压缩此.zip正确。我不知道可能是什么问题。

#Script to Unzip .zip files in downloads folder.

#$src = file you're unzipping, $dest = destination for contents

$src = 'C:\Users\' + $env:USERNAME + '\Downloads\'
$dest = 'C:\Users\' + $env:USERNAME + '\Desktop\Zips\'

Function UnZipper($src, $dest)
{
    Add-Type -AssemblyName System.IO.Compression.FileSystem
    #specifies zip files in directory
    $zps = Get-ChildItem $src -Filter *.zip

    #unpacks each zip in directory to destination folder
    foreach ($zp IN $zps)
    {
        #Sets File Path of original zip
        $Zips = ($src + $zp)
        #Sets destination of zip. Creates folder if it does not exist.
        $NewFolder = $dest + $zp
        $NewFolder = $NewFolder.TrimEnd(".zip")
        #Checks if file already exists (has been unzipped)
        $FileExists = Test-Path $NewFolder
        If ($FileExists -eq $false)
        {
        Write-Host 'UnZipping -'$zp
        [System.IO.Compression.ZipFile]::ExtractToDirectory($Zips, $NewFolder)
        }
    }
}

UnZipper -src $src -dest $dest
Write-Host "Your files have been Un-Zipped!"
Write-Host "Press the enter key to exit and open your file(s)" -ForegroundColor Green
Read-Host
explorer $dest

如果特定的zip最终无法解决，那对我来说很好。我只是想弄清楚为什么它可以与WinZip一起使用，而不能与PowerShell一起使用。

$zps = Get-ChildItem $src -Filter *.zip -File生成一个FileInfo objects数组，您不应像在foreach循环中那样将它们视为简单的文件路径字符串。

最好在需要的地方使用Join-Path cmdlet构造路径：

在下面重新编写函数

function UnZipper {
    [CmdletBinding()]
    param(
        [Parameter(Mandatory = $true, Position = 0)]
        [string]$src,

        [Parameter(Mandatory = $true, Position = 1)]
        [string]$dest
    )
    Add-Type -AssemblyName System.IO.Compression.FileSystem

    # get an array of FileInfo objects for zip files in the $src directory and loop through
    Get-ChildItem $src -Filter *.zip -File | ForEach-Object {
        # unpacks each zip in directory to destination folder
        # the automatic variable '$_' here represents a single FileInfo object, each file at a time

        # Get the destination folder for the zip file. Create the folder if it does not exist.
        $destination = Join-Path -Path $dest -ChildPath $_.BaseName  # $_.BaseName does not include the extension

        # Check if the folder already exists
        if (!(Test-Path $destination -PathType Container)) {
            # create the destination folder
            New-Item -Path $destination -ItemType Directory -Force | Out-Null

            # unzip the file
            Write-Host "UnZipping - $($_.FullName)"
            [System.IO.Compression.ZipFile]::ExtractToDirectory($_.FullName, $destination)
        }
        else {
            Write-Host "Folder '$destination' already exists. File skipped."
        }
    }
}

ExtractToDirectory给出错误“提取Zip条目将导致文件超出指定的目标目录”
