Powershell unzip error

Question

I got a following script from the internet, when I tried to run it gives me an error.

#script
#unzip folder

$shell_app = new-object -com shell.application
$filename = "test.zip"
$zip_file = $shell_app.namespace("C:\temp\$filename")

#set the destination directory for the extracts
$destination = $shell_app.namespace("C:\temp\zipfiles")

#unzip the file
$destination.Copyhere($zip_file.items())

--- Error Message

Answer 1

you need to create the "c:\temp\zipfiles" folder before you set the $destination variable, this kind of sloppy way but it will do the job :)

#script
#unzip folder

$shell_app = new-object -com shell.application
$filename = "test.zip"
$zip_file = $shell_app.namespace("C:\temp\$filename")

#set the destination directory for the extracts
if (!(Test-Path "C:\temp\zipfiles\")) { 
    mkdir C:\temp\zipfiles
}
$destination = $shell_app.namespace("C:\temp\zipfiles")

#unzip the file
$destination.Copyhere($zip_file.items())
