Best way to unzip files in Deploy?

If your targets have PowerShell 5 you can use Expand-Archive. https://stackoverflow.com/a/27771099

If not, you can build a function that calls .NET. https://stackoverflow.com/a/27768628

Add-Type -AssemblyName System.IO.Compression.FileSystem
function Unzip
{
    param([string]$zipfile, [string]$outpath)

    [System.IO.Compression.ZipFile]::ExtractToDirectory($zipfile, $outpath)
}

Unzip "C:\a.zip" "C:\a"

I have this in my PS Profile so that when I'm working with <v5 powershell systems I can easily zip/unzip stuff. Works pretty well:

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

function Unzip-File

{

    param ([string]$Source,

        [string]$Destination)

    

    [System.IO.Compression.ZipFile]::ExtractToDirectory($Source, $Destination)

}

Function Zip-File

{

param([string]$Source,[string]$Destination)

[System.IO.Compression.ZipFile]::CreateFromDirectory($Source,$Destination)

 

}

Hey Colby,

I finally got back around to trying your method, and it does work, if the files don't exist. How do I tell it to overwrite. 

Sorry, still new to powershell....

Which method? Expand-Archive or the Unzip function from StackOverflow?
