Windows – How to extract a tar file (.tgz) in windows

I usually zip the file at the same time by using the 'z' parameter with the tar command:

tar czvf allmyfiles.tar.gz *

The above command creates a new archive file called allmyfiles.tar.gz that contains all the files in the current folder, and zips it.

Otherwise, just delete the .tar file with the next command:

$rm $tarname.TAR

Note that .tar.gz is more commonly used than .tgz.

Here is code that should do what you want (note: It preserves all of the directory structures. If you do not want that, change the x to an e. Run this in powershell)

$cont=true  
cd c:\Extracted  
$TarFilesToExtract = get-childItem *.tar -Recurse  
$TgzFilesToExtract = get-childItem *.tgz -Recurse  
foreach($file in $TarfilesToExtract)  
{   
    7z x $file -oC:\Pathfolder    
}  
foreach($file in $TgzFilesToExtract)    
{  
    7z x $file -oC:\Pathfolder
}  
cd c:\Pathfolder  
while($cont -eq "true")  
{  
    $TarFilesToExtract = get-childItem *.tar -Recurse  
    $TgzFilesToExtract = get-childItem *.tgz -Recurse  
    if($TarFilesToExtract.Length -eq 0 -and $TgzFilesToExtract -eq 0)  
    {  
        $cont = "False"  
    }  
    else  
    {  
        foreach($file in $TarfilesToExtract)  
        {  
            7z x $file  
        }  
        foreach($file in $TgzFilesToExtract)  
        {  
            7z x $file  
        }  
    }  
}  

A shorter simpler version:

$cont=true
cd c:\Extracted
$files = get-childItem -include *.tar,*.tgz -Recurse
foreach($file in $TarfilesToExtract)
{
    7z x $file -oC:\Pathfolder
}
cd c:\Pathfolder  
while($cont -eq "true")
{
    $files = get-childItem -include *.tar,*.tgz -Recurse
    if($files.Length -eq 0)
    {
        $cont = "False"
    }
    else  
    {
        foreach($file in $files)
        {
            7z x $file 
        }
    }
}
