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.."

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。

CodePlex处于只读模式，准备关闭

你可以去PowerShell画廊。

一个纯PowerShell的替代方案，与PowerShell 3和。net 4.5(如果你可以使用它):

function ZipFiles( $zipfilename, $sourcedir )
{
   Add-Type -Assembly System.IO.Compression.FileSystem
   $compressionLevel = [System.IO.Compression.CompressionLevel]::Optimal
   [System.IO.Compression.ZipFile]::CreateFromDirectory($sourcedir,
        $zipfilename, $compressionLevel, $false)
}

只需传入您想要创建的zip归档文件的完整路径，以及包含您想要压缩的文件的目录的完整路径。

下面是sonjz回答的一个稍微改进的版本，它增加了一个覆盖选项。

function Zip-Files(
        [Parameter(Position=0, Mandatory=$true, ValueFromPipeline=$false)]
        [string] $zipfilename,
        [Parameter(Position=1, Mandatory=$true, ValueFromPipeline=$false)]
        [string] $sourcedir,
        [Parameter(Position=2, Mandatory=$false, ValueFromPipeline=$false)]
        [bool] $overwrite)

{
   Add-Type -Assembly System.IO.Compression.FileSystem
   $compressionLevel = [System.IO.Compression.CompressionLevel]::Optimal

    if ($overwrite -eq $true )
    {
        if (Test-Path $zipfilename)
        {
            Remove-Item $zipfilename
        }
    }

    [System.IO.Compression.ZipFile]::CreateFromDirectory($sourcedir, $zipfilename, $compressionLevel, $false)
}

如果有人需要压缩单个文件(而不是一个文件夹):http://blogs.msdn.com/b/jerrydixon/archive/2014/08/08/zipping-a-single-file-with-powershell.aspx
