Ungzip all gz files in Windows

Question

I have many .gz files and I want to unzip all of them keeping their name and folder nesting.

How can I do this with Windows? Does 7zip have functionality that could complete this?

Answer 1

This is the full recursive solution.

@ECHO ON

SET SourceDir=C:\source
FOR /R %SourceDir% %%A IN ("*.gz") DO 7z x "%%~A" -o"%%~pA\"

This doesn't delete original .gz files, I think it can be done with some 7z parameter or simply adding a delete %%~A command in the FOR loop

Answer 2

You can use the x switch and the -o switch with a simple FOR loop using 7zip to complete this task using substitutions accordingly.

The x switch switch tells 7zip to extract files with the full paths. The -o switch specifies the full path to the output directory. The FOR loop %%~NA tells it to name the extracted folder to the same name of the original gz file minus the .gz file extension.

Batch Script Example

@ECHO ON

SET SourceDir=C:\SourceFolder
SET OutputDir=C:\OutputFolder
FOR %%A IN ("%SourceDir%\*.gz") DO 7z x "%%~A" -o"%OutPutDir%\%%~NA"
::::FOR %A IN ("%SourceDir%\*.gz") DO 7z x "%~A" -o"%OutPutDir%\%~NA"
GOTO EOF

In addition, substitution of FOR variable references has been enhanced. You can now use the following optional syntax:

%~I         - expands %I removing any surrounding quotes (")
%~fI        - expands %I to a fully qualified path name
%~dI        - expands %I to a drive letter only
%~pI        - expands %I to a path only
%~nI        - expands %I to a file name only
%~xI        - expands %I to a file extension only
%~sI        - expanded path contains short names only
%~aI        - expands %I to file attributes of file
%~tI        - expands %I to date/time of file
%~zI        - expands %I to size of file
%~$PATH:I   - searches the directories listed in the PATH
               environment variable and expands %I to the
               fully qualified name of the first one found.
               If the environment variable name is not
               defined or the file is not found by the
               search, then this modifier expands to the
               empty string

Answer 3

Winrar has the ability to do this, in the context shell, if you have winrar installed and had it add context menu items, if you highlighted all your archives and then right click, it presents the option to extract each archive into their own separate folder. Whether you use 7zip like the above answer describes from @PIMP_JUICE_IT or Winrar both can accomplish what you are looking for, just one is graphical and the other is not but do as you are wanting.
