powershell Script for unzipping in specific named folder - powershell

Question

I have several zip files which have generated names like 21321421-12315-sad3fse-23434fg-ggfsd which doesn't help to identify the content of the zip.
I need a script, which unzips it and then looks for a pdf file with a partly-generated & static name eg asdawd-ersrfse-231-Formular2311.
After that it should create a folder with the name of the pdf file and unzip all zip-file content into this folder.
So far I only have to snippets that work after each other, but I'm still stuck.
$shell = new-object -com shell.application
$CurrentLocation = get-location
$CurrentPath = $CurrentLocation.path
$Location = $shell.namespace($CurrentPath)
# Find all the Zip files and Count them
$ZipFiles = get-childitem -Path "C:\Install\NB\Teststart" *.zip
$ZipFiles.count | out-default
# Set the Index for unique folders
$Index = 1
# For every zip file in the folder
foreach ($ZipFile in $ZipFiles) {
# Get the full path to the zip file
$ZipFile.fullname | out-default
# Set the location and create a new folder to unzip the files into - Edit the line below to change the location to save files to
$NewLocation = "C:\Install\NB\Testfinal\$Index"
New-Item $NewLocation -type Directory
# Move the zip file to the new folder so that you know which was the original file (can be changed to Copy-Item if needed)
Copy-Item $ZipFile.fullname $NewLocation
# List up all of the zip files in the new folder
$NewZipFile = get-childitem $NewLocation *.zip
# Get the COMObjects required for the unzip process
$NewLocation = $shell.namespace($NewLocation)
$ZipFolder = $shell.namespace($NewZipFile.fullname)
# Copy the files to the new Folder
$NewLocation.copyhere($ZipFolder.items())
# Increase the Index to ensure that unique folders are made
$Index = $Index + 1
}
Get-ChildItem -Path "C:\Install\NB\Testfinal" -Include "*.pdf" -Recurse | ForEach-Object {
$oldFolder = $_.DirectoryName
# New Folder Name is .pdf Filename, excluding extension
$newFolder = $_.Name.Substring(0, $_.Name.Length - 4)
# Verify Not Already Same Name
Write-Host "Rename: $oldFolder To: $newFolder"
Rename-Item -NewName $newFolder -Path $oldFolder
}

Answer 1

Along the same lines as your own script, firstly extract the zips and then rename the extracted folder to the same as the pdf:
$SourceDir = 'C:\Install\NB\Teststart'
$ExtractDir = 'C:\Install\NB\Testfinal'
# Extract each zip to a folder with the same name as the zip file (BaseName)
Get-ChildItem (Join-Path $SourceDir *.zip) | foreach {
Expand-Archive $_.FullName -DestinationPath (Join-Path $ExtractDir $_.BaseName)
}
# Rename the PDF's parent folder to the same as the PDF
Get-ChildItem (Join-Path $ExtractDir *.pdf) -Recurse | foreach {
Rename-Item -Path $_.Directory.FullName -NewName $_.BaseName
}

This should do and it's much simpler than what you have. It relies on .NET 4.5 which you should have on your server already:
[Reflection.Assembly]::LoadWithPartialName('System.IO.Compression.FileSystem')
# Get all the zip files in the root of the script, change $PSScriptRoot accordingly
Get-ChildItem -Path $PSScriptRoot -Filter *.zip -Recurse | ForEach-Object {
# Open the archive for reading
$zip = [IO.Compression.ZipFile]::OpenRead($_.FullName)
# Find the name of the PD file from the archive entries
$archiveName = $zip.Entries | `
Where-Object { [System.IO.Path]::GetExtension($_.FullName) -eq '.pdf' } | `
Select-Object #{N = "BaseName"; E = {[System.IO.Path]::GetFileNameWithoutExtension($_.FullName)}} |
Select-Object -Expand BaseName
# Close the zip file
$zip.Dispose()
# Use the native Expand-Archive to unzip the archive
# Ammand $PSScriptRoot to the destination base path if needed
Expand-Archive -Path $_.FullName -DestinationPath (Join-Path $PSScriptRoot $archiveName)
}
