Compress a folder using powershell

There are many ways to compress a folder using powershell:

Method 1: Using System.IO.Compression and System.IO.Compression.FileSystem

Add-Type -AssemblyName System.IO.Compression
Add-Type -AssemblyName System.IO.Compression.FileSystem

[System.IO.Compression.ZipFile]::CreateFromDirectory($source_WebPortal, $destination_WebPortal,[System.IO.Compression.CompressionLevel]::Fastest,$True)

This method requires .NET Framework 4.5 installed

Method 2: Using pure Powershell script

function Add-Zip
{
    param([string]$zipfilename)

    if(-not (test-path($zipfilename)))
    {
        set-content $zipfilename ("PK" + [char]5 + [char]6 + ("$([char]0)" * 18))
        (dir $zipfilename).IsReadOnly = $false    
    }
    
    $shellApplication = new-object -com shell.application
    $zipPackage = $shellApplication.NameSpace($zipfilename)
    
    foreach($file in $input) 
    { 
            $zipPackage.CopyHere($file.FullName)
            Start-sleep -milliseconds 200
    }
}

dir $tempFolder\*.* -Recurse | add-Zip $zipFile

This method can be run at powershell 2.0 and .NET Framework 4.0
