Do you have code that works up to a point?

If you are trying to work with zip files powershell 5 does have some commands to help. see

This will delete the folder and file from your zips.

$zip = Get-ChildItem \\path\to\zips -Filter *.zip
add-type -AssemblyName 'System.IO.Compression.filesystem'

# Change zip file
foreach ($z in $zip){
    Write-Verbose "Updating $($" -Verbose
    $tempz = [io.compression.zipfile]::Open($z.FullName,'Update')
    $entry = $tempz.Entries | Where-Object {
    $_.fullname -match 'queryTables|connections.xml'}
    foreach ($e in $entry){$e.Delete()}

Check PSVersion and CLRVersion (.NET Version)
What versions of PowerShell and .NET are installed? I tested it with PS:3.0 / CLR:4.0.30319.42000.
Update .NET and at least to PS 3.0
