How to unzip multiple zip folders

Question

I am trying to achieve one requirement that I have nested zip files there. I need to Unzip all those by single click. For that I have a code wich is working only for one zipped folder and need to expand this. below is the code which I need to expand:

Add-Type -AssemblyName System.IO.Compression.FileSystem
function Unzip
{
param([string]$zipfile, [string]$outpath)
[System.IO.Compression.ZipFile]::ExtractToDirectory($zipfile, $outpath)
}
Unzip "E:\Softwares\PS\AllFiles.zip" "E:\Softwares\PS\AllFiles"

Can any one suggest me a way to expand this to unzip the nested zip folders..

Answer 1

Your question isn't very detailed. I played with a little by having a file on C:\\temp\\ziptest that I placed multiple nested zip files in and this worked. Please note there could be a lot more variables that need to be accounted for (ie zip files have password, are they standard zip file or .7z, etc).

Add-Type -AssemblyName System.IO.Compression.FileSystem
function Unzip
{
  param([string]$zipfile, [string]$outpath)
  [System.IO.Compression.ZipFile]::ExtractToDirectory($zipfile, $outpath)
}



$flag = $true
while($flag)
{
 $zipFiles = Get-ChildItem -Path "C:\temp\ziptest" -Recurse | Where-Object {$_.Name -like "*.zip"}

 if($zipFiles.count -eq 0)
 {
    $flag = $false
 }

 elseif($zipFiles.count -gt 0)
 {
    foreach($zipFile in $zipFiles)
    {
     #create the new name without .zip
     $newName = $zipFile.FullName.Replace(".zip", "")

     Unzip $zipFile.FullName $newName

     #remove zip file after unzipping so it doesn't repeat 
     Remove-Item $zipFile.FullName   
    }
 }
 Clear-Variable zipFiles
}
