Copy Files from ZIP archives

PowerShell Help
1

I have a script to copy files from one location to another based on an input file.

The input file is in the format:

C:\Store\firstfile.txt
C:\Store\secondfile.txt
etc.

This all works fine, but the input file also contains references to a file within a zip file in the format:

C:\Store\Logs\mylog.zip\filetobecopied.txt

Where filetobecopied.txt is inside mylog.zip. The zip file may also contain a folder structure, e.g

C:\Store\Logs\mylog.zip\Reports\filetobecopied.txt.

I’ve tried the following so far, but no success (powershell v3)

get-content $sourceFile | foreach-object {

$FileToCopy = $_
if ($FileToCopy.Contains(".zip")) {
            
    $FileToCopy = $FileToCopy.Substring(0, $s.IndexOf('.zip')) + '.zip'
    }              
    $ObjSourceFile = get-item $FileToCopy

$SourceFileName = $ObjSourceFile.name
$SourceDirectory = $objSourceFile.DirectoryName

Is there a way of achieving this?

You can’t read a file directly from a ZIP; you would need to first expand the ZIP.

You can do this with a Shell.Application COM object.
My test file robots.zip contains a file called robots.txt

$shellApp = New-Object -ComObject Shell.Application
$destination = 'F:\' 
$fileToCopy = 'F:\__Temp\robots.zip\robots.txt'
$shellApp.NameSpace($destination).copyhere($fileToCopy)

Thanks Matt, that was exactly what I was looking for.
