Here is an example in which I find aes.h inside the ffmpeg source code zip archive: ::LoadWithPartialName('System.IO.Compression') Ordinary zip file in memoryĪs a bonus, let's see how it works with ZIP. This option tells tar to display the names of the files being extracted on the terminal. For more verbose output, use the -v option. Tar auto-detects the compression type and extracts the archive. To extract a tar.xz file, invoke the tar command with the -extract ( -x) option and specify the archive file name after the -f option: tar -xf. Since the Windows 10 Preview Build 17063, bsdtar is included with PowerShell. However, 7Zip4PowerShell does not implement all the overloaded method signatures of SevenZipExtractor Import-Module -Name 7Zip4Powershell -Global If we were writing the file to disk, the objective is more simple to achieve using the 7Zip4Powershell module. Here is a working example I wrote that implements the above approach to download and install ffmpeg. $szExtractor = New-Object -TypeName SevenZipExtractor.ArchiveFile -ArgumentList # Instead of $env:TEMP, wherever you want the files to go So we can use the SevenZipExtractor class by $sevenZipStream = ::new(($r.Content)) Here Stream means data-type System.IO.Stream and SevenZipFormat means type SevenZipExtractor.SevenZipFormat. Public SevenZipExtractor(Stream archiveStream, string password, InArchiveFormat format) Public SevenZipExtractor(Stream archiveStream, SevenZipFormat format) Public SevenZipExtractor(Stream archiveStream, string password) The SevenZipExtractor class includes, inter alia, the following overloaded constructor signatures: public SevenZipExtractor(Stream archiveStream) (Get-Item (Join-Path (Split-Path (Get-Package SevenZipExtractor).Source) lib/netstandard*) | #Add the SevenZip assembly to our current PowerShell session Install-Package SevenZipExtractor -Scope CurrentUser Using SevenZipExtractor C# wrapper for 7Zip, we extract as follows: #Download and install from Our target archive is available to shell as a byte array in $r.Content. We can download without writing to disk as follows: $r=Invoke-WebRequest -Uri '' Without writing anything to diskīy example, suppose we want to download/extract files from the XZ archive available at MinGW - Minimalist GNU for Windows. I describe two approaches to achieve the objective. Challenge: Download, extract xz archive in PowerShell
