Stuck on overwrite question unzipping files

Question

Hi guys!
I've created a script that extract zip files (7z and zip extensions) but i've got a problem with overwriting.
Clear-Host
Function Find-Files(){
[CmdletBinding()]
param(
[Parameter(Mandatory=$true,Position=0)][string]$Path,
[Parameter(Mandatory=$true,Position=1)][string]$Code
$Test=0
$WorkFiles=@()
$Unzipped=@()
$AllFiles=Get-ChildItem -Path $Path -Recurse -File
foreach( $item in $AllFiles|Where{ $_.Name -like "sin*.dat" } ){
$WorkFiles+= $item.FullName
$ZipFiles=$AllFiles|Where{($_.Extension -eq ".7z") -or ($_.Extension -eq ".zip")}
if( $ZipFiles.Length -ne 0 ){
$Test=1
Set-Alias 7zip "$env:ProgramFiles\7-Zip\7z.exe"
$Directory="D:\ZTemp"
if((Test-Path $Directory) -eq $false){
mkdir $Directory
foreach ($Zip in $ZipFiles){
$Name=$Zip.BaseName
$Destination=$Directory,$Name -join('\')
if( Test-Path $zip.Name ){
Write-Error "Sono presenti Cartelle compresse con nomi uguali $Destination" -Category SecurityError
$Unzipped+= $Zip.FullName
$foreach.movenext()
#continue
cd $Zip.Directory.FullName
7zip 'x' $Zip.Name "-o$Destination"
$ExtFiles= Get-ChildItem $Destination -File -Recurse|Where-Object{ $_.Name -like "sin*.dat"}
if ($ExtFiles.count -eq 0){
Remove-Item $Destination -Recurse -Force
else{
foreach ($item in $ExtFiles){
$WorkFiles+=$item.FullName
cd $env:HOME

 launching this script i'm stuck here:
Please tell me how to go ahead with this problem.

Answer 1

This is a 7Zip command issue.  You need to set the zip command correctly.  If you do not know how to use 7zip then post in the 7zip forum.
You can get the arguments from 7zip "7z /?"
¯\_(ツ)_/¯
