I want to extract all .zip files in a given directory in temp using powershell


Tag: powershell,unzip

I wrote the following code for extracting the .zip files to temp:

function Expand-ZIPFile($file, $destination)
    $shell = new-object -com shell.application
    $zip = $shell.NameSpace($file)
    foreach ($item in $zip.items()) {

Expand-ZIPFile -file "*.zip" -destination "C:\temp\CAP"

But I got the following error:

PS C:\Users\v-kamoti\Desktop\CAP> function Expand-ZIPFile($file, $destination)
   $shell = new-object -com shell.application
   $zip = $shell.NameSpace($file)
   foreach ($item in $zip.items()) {

Expand-ZIPFile -file "*.zip" -destination "C:\temp\CAP"
You cannot call a method on a null-valued expression.
At line:5 char:19

You have to provide the full path explicitly (without wildcards) in the following call:


You could rewrite your function like this:

function Expand-ZIPFile($file, $destination)
    $files = (Get-ChildItem $file).FullName

    $shell = new-object -com shell.application

    $files | %{
        $zip = $shell.NameSpace($_)

        foreach ($item in $zip.items()) {
