PowerShell – Create Zip File

Posted on By David Kittell

Scenario, you’re on a Windows Server and don’t want to or can’t install a zip program.

This script will help you create a zip file without any special program.

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)
}

ZipFiles c:\Drivers.zip D:\
