"Extracting the zip file to below location: " + $archiveFile
"Destination location : " + $destination
#$ErrorActionPreference = "SilentlyContinue"

When you get that error, what’s in your $archiveFile variable? One potential problem that stands out here is this:

```
$files = Get-ChildItem $spath -include test*.zip -Recurse

foreach ($file in $files) 
{
    $archiveFile = $spath + $file.Name | out-string -stream
```

You’re using the -Recurse switch for Get-ChildItem, which means that you could potentially be finding files such as “$spath\SubFolder\testSomething.zip”. However, when you set up your $archiveFile variable, it would just contain “$spath\testSomething.zip”, which probably wouldn’t exist. Instead, you can just say $archiveFile = $file.FullName , which will automatically have the full path to the file and avoid such problems. I don’t know if that’s what’s causing your current failure, though; you’d have to test and see.
