Windows – Automatically extract and rename extracted file according to archive’s name

7-zipcommand linewindows 7

I have a bunch of zip files in a folder. Each zip file has a file in it named exp_1.txt. I would like to unzip each zip file and rename the extracted file from each zip file to what the zip file was named.

The zip files names don't follow any pattern or date structure, but are all different. I have figured out how to get the exp_1.txt file extracted into the same directory as the zip file, but can't figure out the renaming of exp_1.txt to match what the zip file it was extracted from is named.

Once again in fewer words: from TuesdayReport.zip I want to extract the only file exp_1.txt and rename it to TuesdayReport.txt in the same directory as TuesdayReport.zip.

Currently I'm using 7z x to extract the file to the same directory the zip file is located in. I would prefer to be able to run this from a batch file.

why not using 7zip command line edition, that you can download from here?

inside this zip file you can find a help file in CHm format that has all switches and commands that can help you during your batch process.

As far as I can tell, 7-zip doesn't have a command that does what you're looking for. Here's a Windows batch file script which I think will do what you want. It should be run from the command line so you can supply a path to the root of the folder tree to be processed.

File unzipper.bat

@echo off
setlocal
if "%1"=="" goto Usage

call :Get7zCmd
:: Recurse folder passed in as paramater
for /r %1 %%Z in (*.zip) do (
    echo ====
    rem Change to the directory of zip file
    cd /d "%%~dpZ"
    rem Extract all files to current directory
    echo %_7zCmd% e "%%~nxZ" -y
    rem Delete the zip file
    echo del "%%~nxZ"
)
goto End

:Usage
echo.
echo Parses through folder structure starting at the specified path, finding
echo and extracting the contents of all zip files found, and then deletes
echo the zip file.
echo.
echo Usage:
echo     %~n0 root-directory-path
echo.
echo     For example:
echo.
echo %~n0 "D:\some folder"

:End
goto :EOF

:: ==========================
:: Subroutine Get7zCmd
:: Determines the full path to 7-zip command-line executable from the Windows
:: Registry and sets the variable "_7zCmd" to the result.
:Get7zCmd
set Reg.Key=HKLM\Software\Microsoft\Windows\CurrentVersion\App Paths\7zFM.exe
set Reg.Val=Path
for /F "Tokens=2*" %%A in ('Reg Query "%Reg.Key%" /v "%Reg.Val%" ^| find /I "%Reg.Val%"') do call set PathDirectory=%%B
set _7zCmd="%PathDirectory%%\7z.exe"
exit /b 0

Since as a whole what the script does is fairly radical and potentially destructive because it might extract large numbers of file and delete many zip files afterward, I've disabled the commands on lines 12 and 14 which would do those things by prefixing them with echo. This make them just print out what they would have done if the echo wasn't there. That way you can test the script first without doing any damage to your file system should there be some sort of unexpected problem.

To modify the script actually perform these actions, you'll need to remove the echo on each of the two lines. Standard disclaimer of any liability applies, of course.

Extract .7z archive keeping modified dates of extracted folders

Extracted folders have the created/modified date set to the time/date of extraction

This is a known feature request (#1174), Status: open.

#1174 Preserve original file creating\edit dates when extracting

Now when files are extracted their creating date, edited date are set to current time despite in archive they could have their own dates, an option to preserve those would be very nice.

...

The hard part is already done. If you just right-click and under 7-zip, extract here/to, it should perform as expected.

After testing it appears that the above comment is incorrect and doesn't work.
