I am using 7-Zip on Windows XP and whenever I download a .tar.gz file it takes me two steps to completely extract the file(s).
example.tar.gz file and choose 7-Zip --> Extract Here from the context menu.example.tar file and the right-click again and choose 7-Zip --> Extract Here from the context menu.Is there a way through the context menu to do this in one step?
Not really. A .tar.gz or .tgz file really is two formats: .tar is the archive, and .gz is the compression. So the first step decompresses, and the second step extracts the archive.
To do it all in one step, you need the tar program. Cygwin includes this.
tar xzvf foobaz.tar.gz
; x = eXtract
; z = filter through gZip
; v = be Verbose (show activity)
; f = filename
You could also do it "in one step" by opening the file in the 7-zip GUI: Open the .tar.gz file, double click the included .tar file, then extract those files to your location of choice.
There's a long running thread here of people asking/voting for one-step handling of tgz and bz2 files. The lack action thus far indicates it's not going to happen until someone steps and contributes meaningfully (code, money, something).
Old question, but I was struggling with it today so here's my 2c. The 7zip commandline tool "7z.exe" (I have v9.22 installed) can write to stdout and read from stdin so you can do without the intermediate tar file by using a pipe:
7z x "somename.tar.gz" -so | 7z x -aoa -si -ttar -o"somename"
Where:
x = Extract with full paths command
-so = write to stdout switch
-si = read from stdin switch
-aoa = Overwrite all existing files without prompt.
-ttar = Treat the stdin byte stream as a TAR file
-o = output directory
See the help file (7-zip.chm) in the install directory for more info on the command line commands and switches.
You can create a context menu entry for .tar.gz/.tgz files that calls the above command using regedit or a 3rd party tool like stexbar.
Starting with 7-zip 9.04 there is a command-line option to do the combined extraction without using intermediate storage for the plain .tar file:
7z x -tgzip -so theinputfile.tgz | 7z x -si -ttar
-tgzip is needed if the input file is named .tgz instead of .tar.gz.
Starting from Windows 10 build 17063, tar and curl are supported, therefore it is possible to unzip a .tar.gz file in one step by using tar command, as below.
tar -xzvf your_archive.tar.gz
Type tar --help for more information about tar.
You're using Windows XP, so you should have Windows Scripting Host installed by default. With that being said, here's a WSH JScript script to do what you need. Just copy the code to a file name xtract.bat or something along those lines (Can be whatever as long as it has the extension .bat), and run:
xtract.bat example.tar.gz
By default, the script will check the folder of the script, as well as your system's PATH environment variable for 7z.exe. If you want to change how it looks for stuff, you can change the SevenZipExe variable at the top of the script to whatever you want the executable name to be. (For instance, 7za.exe or 7z-real.exe) You can also set a default directory for the executable by changing SevenZipDir. So if 7z.exe is at C:\Windows\system32\7z.exe, you'd put:
var SevenZipDir = "C:\\Windows\\system32";
Anyways, here's the script:
@set @junk=1 /* vim:set ft=javascript:
@echo off
cscript //nologo //e:jscript "%~dpn0.bat" %*
goto :eof
*/
/* Settings */

As you can see 7-Zip is not very good at this. People have been asking for tarball atomic operation since 2009. As an alternative, you can use the Arc program. Example command:
arc unarchive test.tar.gz
I am using 7zip v19.00, just right click and choose extract here will do the work. Although 7zip issues warning, the result is fine for me.
7za is work properly as below:
7za.exe x D:\pkg-temp\Prod-Rtx-Service.tgz -so | 7za.exe x -si -ttar -oD:\pkg-temp\Prod-Rtx-Service
