Include top level directory into zip file created by PowerShell - powershell

Question

The code below zips the following files:
c:\test\1.txt
c:\test\2.txt
c:\test\3.txt
into test.zip like:
1.txt
2.txt
3.txt
but what I would like is to include the directory test:
test\1.txt
test\2.txt
test\3.txt
Any idea on how to do this?
$zipFilename = 'c:\test.zip'
$zipDir = 'c:\test'
Set-Content $zipFilename ("PK" + [char]5 + [char]6 + ("$([char]0)" * 18))
$shell = New-Object -ComObject Shell.Application
$zipPackage = $shell.NameSpace($zipFilename)
Get-ChildItem $zipDir -Recurse | foreach {
# echo $_.FullName
$zipPackage.CopyHere($_.FullName)
Start-Sleep -Milliseconds 1000
}

Answer 1

Do you have a reason to loop through the files?
You could just skip the loop and outright zip the files/folder structure
$zipFilename = 'c:\test.zip'
$zipDir = 'c:\test'
Set-Content $zipFilename ("PK" + [char]5 + [char]6 + ("$([char]0)" * 18))
$shell = New-Object -ComObject Shell.Application
$zipPackage = $shell.NameSpace($zipFilename)
$zipPackage.CopyHere($zipDir)
If you have additional processing you could add a dynamic sleep. Wait a second per file.
Sleep (Get-childitem $zipDir -recurse | Measure-Object | Select-Object -expandproperty Count)
