How to move a single txt file to the zip in powershell 3

Question

I am trying to copy/move one text file to the zip. I don't want to unzip it, copy the file and zip it back. Is there any way we can directly copy or move text file to the zip in powershell. When i am doing it in powershell, it's doing after that when i try to look inside the zip it's saying invalid path.

Powershell commands:

$A = "20160914.4"

New-Item "C:\test\VersionLabel.txt" -ItemType file

$A | Set-Content "C:\test\VersionLabel.txt"

Copy-Item "C:\test\VersionLabel.txt" "C:\test\Abc.zip"  -Force

Error: The compressed folder is invalid

[How to create a zip archive with PowerShell?](https://stackoverflow.com/a/12978117) you can do it manually via ZipArchive or ZipPackage or zip folder namespace. The linked question has many answers. — wOxxOm, Sep 14 '16 at 20:15

>= PowerShell 5.0

Per @SonnyPuijk's answer above, use Compress-Archive.

clear-host
[string]$zipFN = 'c:\temp\myZipFile.zip'
[string]$fileToZip = 'c:\temp\myTestFile.dat'
Compress-Archive -Path $fileToZip -Update -DestinationPath $zipFN

< PowerShell 5.0

To add a single file to an existing zip:

clear-host
Add-Type -assembly 'System.IO.Compression'
Add-Type -assembly 'System.IO.Compression.FileSystem'

[string]$zipFN = 'c:\temp\myZipFile.zip'
[string]$fileToZip = 'c:\temp\myTestFile.dat'
[System.IO.Compression.ZipArchive]$ZipFile = [System.IO.Compression.ZipFile]::Open($zipFN, ([System.IO.Compression.ZipArchiveMode]::Update))
[System.IO.Compression.ZipFileExtensions]::CreateEntryFromFile($ZipFile, $fileToZip, (Split-Path $fileToZip -Leaf))
$ZipFile.Dispose()

To create a single file zip file from scratch:

Same as above, only replace: [System.IO.Compression.ZipArchiveMode]::Update

With: [System.IO.Compression.ZipArchiveMode]::Create

You can use Compress-Archive for this. Copy-Item doesn't support zip files.

If you don't have PowerShell v5 you can use either 7Zip command line or .Net

Only other method I know is using the dotnet library. Scripting guy already wrote a blog about this. https://blogs.technet.microsoft.com/heyscriptingguy/2015/03/09/use-powershell-to-create-zip-archive-of-folder/ – Sonny Puijk Sep 14 '16 at 20:15
