How can I compress (/ zip ) and uncompress (/ unzip ) files and folders with batch file without using any external tools?
And here are the answer(s):
1. Using "pure" batch script to zip/unzip file.
It's possible thanks to Frank Westlake's ZIP.CMD and UNZIP.CMD(needs admin permissions and requires FSUTIL
and CERTUTIL
) .For Win2003 and WinXP it will require 2003 Admin Tool Pack which will install CERTUTIL
. Be careful as ZIP.CMD syntax is backward :
ZIP.CMD destination.zip source.file
And it can zip only single files.
2. Using Shell.Application
I've spent some time to create a single jscript/batch hybrid script for common usage that zips/unzips files and directories (plus few more features).Here's a link to it (it became too big to post in the answer).
Can be used directly with its .bat
extension and does not create any temp files.
I hope the help message is descriptive enough of how it can be used.
Some examples:
// unzip content of a zip to given folder.content of the zip will be not preserved (-keep no).Destination will be not overwritten (-force no)
call zipjs.bat unzip -source C:\myDir\myZip.zip -destination C:\MyDir -keep no -force no
// lists content of a zip file and full paths will be printed (-flat yes)
call zipjs.bat list -source C:\myZip.zip\inZipDir -flat yes
// lists content of a zip file and the content will be list as a tree (-flat no)
call zipjs.bat list -source C:\myZip.zip -flat no
// prints uncompressed size in bytes
zipjs.bat getSize -source C:\myZip.zip
// zips content of folder without the folder itself
call zipjs.bat zipDirItems -source C:\myDir\ -destination C:\MyZip.zip -keep yes -force no
// zips file or a folder (with the folder itslelf)
call zipjs.bat zipItem -source C:\myDir\myFile.txt -destination C:\MyZip.zip -keep yes -force no
// unzips only part of the zip with given path inside
call zipjs.bat unZipItem -source C:\myDir\myZip.zip\InzipDir\InzipFile -destination C:\OtherDir -keep no -force yes
call zipjs.bat unZipItem -source C:\myDir\myZip.zip\InzipDir -destination C:\OtherDir
// adds content to a zip file
call zipjs.bat addToZip -source C:\some_file -destination C:\myDir\myZip.zip\InzipDir -keep no
call zipjs.bat addToZip -source C:\some_file -destination C:\myDir\myZip.zip
Some known issues during zipping:
- if there's not enough space on the system drive (usually C:) the script could produce various errors , most often the script halts.This is due to Shell.Application actively uses %TEMP% folder to compress/decompress the data.
- Folders and files that contain unicode symbols in their names cannot be handled by Shell.Application object.
- Max supported size of produced zip files is around 8gb in Vista and above and around 2gb in XP/2003
The script detects if error message pops-up and stops the execution and informs for the possible reasons.At the moment I have no way to detect the text inside the pop-up and give the exact reason for the failure.
3. Makecab
Compressing a file is easy - makecab file.txt "file.cab"
. Eventually MaxCabinetSize could be increased.
Compressing a folder requires a usage DestinationDir directive (with relative paths) for every (sub)directory and the files within .
Here's a script:
;@echo off
;;;;; rem start of the batch part ;;;;;
;
;for %%a in (/h /help -h -help) do (
; if /I "%~1" equ "%%~a" if "%~2" equ "" (
; echo compressing directory to cab file
; echo Usage:
; echo(
; echo %~nx0 "directory" "cabfile"
; echo(
; echo to uncompress use:
; echo EXPAND cabfile -F:* .
; echo(
; echo Example:
; echo(
; echo %~nx0 "c:\directory\logs" "logs"
; exit /b 0
; )
; )
;
; if "%~2" EQU "" (
; echo invalid arguments.For help use:
; echo %~nx0 /h
; exit /b 1
;)
;
; set "dir_to_cab=%~f1"
;
; set "path_to_dir=%~pn1"
; set "dir_name=%~n1"
; set "drive_of_dir=%~d1"
; set "cab_file=%~2"
;
; if not exist %dir_to_cab%\ (
; echo no valid directory passed
; exit /b 1
;)
;
;break>"%tmp%\makecab.dir.ddf"
;
;setlocal enableDelayedExpansion
;for /d /r "%dir_to_cab%" %%a in (*) do (
;
; set "_dir=%%~pna"
; set "destdir=%dir_name%!_dir:%path_to_dir%=!"
; (echo(.Set DestinationDir=!destdir!>>"%tmp%\makecab.dir.ddf")
; for %%# in ("%%a\*") do (
; (echo("%%~f#" /inf=no>>"%tmp%\makecab.dir.ddf")
; )
;)
;(echo(.Set DestinationDir=!dir_name!>>"%tmp%\makecab.dir.ddf")
; for %%# in ("%~f1\*") do (
;
; (echo("%%~f#" /inf=no>>"%tmp%\makecab.dir.ddf")
; )
;makecab /F "%~f0" /f "%tmp%\makecab.dir.ddf" /d DiskDirectory1=%cd% /d CabinetNameTemplate=%cab_file%.cab
;rem del /q /f "%tmp%\makecab.dir.ddf"
;exit /b %errorlevel%
;;
;;;; rem end of the batch part ;;;;;
;;;; directives part ;;;;;
;;

.set GenerateInf=OFF

.Set UniqueFiles=ON
.Set MaxDiskSize=1215751680;
.set RptFileName=nul
.set InfFileName=nul

;;
;;;; end of directives part ;;;;;
Example usage:
call cabDir.bat ./myDir compressedDir.cab
For decompression EXPAND cabfile -F:* .
can be used.For extraction in Unix cabextract or 7zip can be used.
4. .NET and GZipStream
I preferred a Jscript.net as it allows a neat hybridization with .bat (no toxic output , and no temp files).Jscript does not allow passing a reference of object to a function so the only way I found to make it work is by reading/writing files byte by byte (so I suppose it's not the fastest way - how buffered reading/writing can be done?)Again can be used only with single files.
@if (@X)==(@Y) @end /* JScript comment
@echo off
setlocal
for /f "tokens=* delims=" %%v in ('dir /b /s /a:-d /o:-n "%SystemRoot%\Microsoft.NET\Framework\*jsc.exe"') do (
set "jsc=%%v"
)
if not exist "%~n0.exe" (
"%jsc%" /nologo /out:"%~n0.exe" "%~dpsfnx0"
)
%~n0.exe %*
endlocal & exit /b %errorlevel%

var arguments:String[] = Environment.GetCommandLineArgs();
function printHelp(){
Console.WriteLine("Compress and uncompress gzip files:");
Console.WriteLine("Compress:");
Console.WriteLine(arguments[0]+" -c source destination");

break;
case "-u":
UncompressFile(arguments[2],arguments[3]);
break;
default:

printHelp();
Environment.Exit(1);
}
Example usage:
//zip
call netzip.bat -c my.file my.zip
//unzip
call netzip.bat -u my.zip my.file
5. TAR (only for the newest windows builds)
With the latest builds of windows 10 now we have TAR command ,though it's not the most backward compatible option:
//compress directory
tar -cvf archive.tar c:\my_dir
//extract to dir
tar -xvf archive.tar.gz -C c:\data
//compres to zip format
tar -caf archive.zip c:\my_dir
amazing solutions!
The makecab solution has some issues so here is a fixed version that solves the problem when using directories with blank spaces.

Some examples with powershell using Compress-Archive and Expand-Archive:
//zipping folder or file:
powershell "Compress-Archive -Path """C:\some_folder""" -DestinationPath """zippedFolder.zip""""
//unzipping folder:
powershell "Expand-Archive -Path """Draftv2.Zip""" -DestinationPath """C:\Reference""""
As in the current supported versions of windows these cmd-lets are installed by default.
Another ways with powershell
//zip directory
powershell "Add-Type -Assembly """System.IO.Compression.FileSystem""" ;[System.IO.Compression.ZipFile]::CreateFromDirectory("""C:\some_dir""", """some.zip""");"
//unzip directory
powershell "Add-Type -Assembly "System.IO.Compression.FileSystem" ;[System.IO.Compression.ZipFile]::ExtractToDirectory("""yourfile.zip""", """c:\your\destination""");"
