Microsoft implemented a <a href="https://msdn.microsoft.com/en-us/library/system.io.compression.gzipstream%28v=vs.110%29.aspx" rel="nofollow">gzipstream in System.IO.Compression</a> in .Net 2.0 There are tons of examples in C# and many others in powershell. The <a href="https://pscx.codeplex.com/" rel="nofollow">Powershell Community Extensions</a> also have Write-Zip and Write-Tar functions. Here is a function for gzip I did quite a while back. It should really be updated to handle multiple inputs and better output naming. It also only handles one file at a time. But it should get you started if you want to see how its done.

<pre><code>function New-GZipArchive
{
 [CmdletBinding(SupportsShouldProcess=$true, 
 PositionalBinding=$true)]
 [OutputType([Boolean])]
 Param
 (
 # The input file(s)
 [Parameter(Mandatory=$true, 
 ValueFromPipeline=$true,
 Position=0)]
 [ValidateNotNull()]
 [ValidateNotNullOrEmpty()]
 [ValidateScript({Test-Path $_})]
 [String]
 $fileIn,

 # The path to the requested output file
 [Parameter(Position=1)]
 [ValidateNotNull()]
 [ValidateNotNullOrEmpty()]
 #validation is done in the script as the only real way to determine if it is a valid path is to try it
 [String]
 $fileOut,

 # Param3 help description
 [Switch]
 $Clobber
 )
 Process
 {
 if ($pscmdlet.ShouldProcess("$fileIn", "Zip file to $fileOut"))
 {
 if($fileIn -eq $fileOut){
 Write-Error "You can't zip a file into itself"
 return
 }
 if(Test-Path $fileOut){
 if($Clobber){
 Remove-Item $fileOut -Force -Verbose
 }else{
 Write-Error "The output file already exists and the Clobber parameter was not specified. Please input a non-existent filename or specify the Clobber parameter"
 return
 }
 }
 try{
 #create read stream 
 $fsIn = New-Object System.IO.FileStream($fileIn, [System.IO.FileMode]::Open, [System.IO.FileAccess]::Read, [System.IO.FileShare]::Read)
 #create out stream
 $fsOut = New-Object System.IO.FileStream($fileOut, [System.IO.FileMode]::CreateNew, [System.IO.FileAccess]::Write, [System.IO.FileShare]::None)
 #create gzip stream using out file stream
 $gzStream = New-Object System.IO.Compression.GZipStream($fsout, [System.IO.Compression.CompressionMode]::Compress)
 #create a shared buffer
 $buffer = New-Object byte[](262144) #256KB
 do{
 #read into buffer
 $read = $fsIn.Read($buffer,0,262144)
 #write buffer back out
 $gzStream.Write($buffer,0,$read)
 }
 while($read -ne 0)
 }
 catch{
 #really should add better error handling
 throw
 }
 finally{
 #cleanup

Usage:

blocks|key|607718|text|另一种可能是调用Windows现在支持的原生tar命令(使用gzip压缩)：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|607719|tar+-cvzf+filename.tgz+mydir|code-block|syntax|javascript|607720|https://techcommunity.microsoft.com/t5/Containers/Tar-and-Curl-Come-to-Windows/ba-p/382409|offset|length|607721|entityMap|0|LINK|mutability|MUTABLE|url^0|0|0|0|2I|0|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|S|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|T|8|@]|9|@$I|U|J|V|1|W]]|A|$]]|$1|K|3|-4|5|6|7|X|8|@]|9|@]|A|$]]]|L|$M|$5|N|O|P|A|$Q|H]]]]

Another possibility is to call out to the native tar command that Windows now supports (with gzip compression):

<pre class="lang-powershell prettyprint-override"><code>tar -cvzf filename.tgz mydir
</code></pre>

I'm searching for solution to solve problem with creating tar.gz archive using Powershell v4. I couldn't find extensions/packets created or verified by Microsoft to provide such functionality. Do such solutions exist [tar-ing and gzip-ing]?
