这很晦涩，但很有效。7za.exe是7zip的独立版本，可通过安装包获得。

# get files to be send
$logFiles = Get-ChildItem C:\Logging\*.* -Include *.log | where {$_.Name -match $yesterday} 

foreach ($logFile in $logFiles)
{
    Write-Host ("Processing " + $logFile.FullName)

    # compress file
    & ./7za.exe a -mmt=off ($logFile.FullName + ".7z") $logFile.FullName

}

下面是工作代码，压缩源文件夹中的所有文件，并在目标文件夹中创建一个zip文件。

    $DestZip="C:\Destination\"
    $Source = "C:\Source\"

    $folder = Get-Item -Path $Source

    $ZipTimestamp = Get-Date -format yyyyMMdd-HHmmss;
    $ZipFileName  = $DestZip + "Backup_" + $folder.name + "_" + $ZipTimestamp + ".zip" 

    $Source

    set-content $ZipFileName ("PK" + [char]5 + [char]6 + ("$([char]0)" * 18)) 
    # Wait for the zip file to be created.
    while (!(Test-Path -PathType leaf -Path $ZipFileName))
    {    
        Start-Sleep -Milliseconds 20
    } 
    $ZipFile = (new-object -com shell.application).NameSpace($ZipFileName)

    Write-Output (">> Waiting Compression : " + $ZipFileName)       

    #BACKUP - COPY
    $ZipFile.CopyHere($Source) 

    $ZipFileName
    # ARCHIVE

    Read-Host "Please Enter.."

下面是PowerShell v5的原生解决方案，使用cmdlet压缩-归档使用PowerShell创建Zip文件。

请参见微软文档 Compress-Archive。

示例1:

Compress-Archive `
    -LiteralPath C:\Reference\Draftdoc.docx, C:\Reference\Images\diagram2.vsd `
    -CompressionLevel Optimal `
    -DestinationPath C:\Archives\Draft.Zip

示例2:

Compress-Archive `
    -Path C:\Reference\* `
    -CompressionLevel Fastest `
    -DestinationPath C:\Archives\Draft

示例3:

Write-Output $files | Compress-Archive -DestinationPath $outzipfile

Windows下压缩解压目录的完整命令行如下:

压缩: powershell.exe -nologo -noprofile -command "&{添加- type -A 'System.IO.Compression.FileSystem';[IO.Compression.ZipFile]:: CreateFromDirectory (C: \印度河,“C: \ Indus.zip”);}” 提取: powershell.exe -nologo -noprofile -command "& {Add-Type -A 'System.IO.Compression.FileSystem';[IO.Compression.ZipFile]::ExtractToDirectory('C:\ industrial .zip'，'C:\Indus');}”

如果您前往CodePlex并获取PowerShell社区扩展，您可以使用他们的write-zip cmdlet。
