I have a batch file that outputs a text file. I thought it would be nice if I could zip it up too.
This will be used in an uncontrolled environment, so I can't make assumptions about the presence of third-party software products such as 7-Zip, etc. This needs to use Windows' now-built-in capability to zip files.

Here is an all batch file solution (a variation of my other answer) that will zip a file named c:\ue_english.txt and put it in C:\someArchive.zip:
set FILETOZIP=c:\ue_english.txt
set TEMPDIR=C:\temp738
rmdir %TEMPDIR%
mkdir %TEMPDIR%
xcopy /s %FILETOZIP% %TEMPDIR%
echo Set objArgs = WScript.Arguments > _zipIt.vbs
echo InputFolder = objArgs(0) >> _zipIt.vbs
echo ZipFile = objArgs(1) >> _zipIt.vbs
echo CreateObject("Scripting.FileSystemObject").CreateTextFile(ZipFile, True).Write "PK" ^& Chr(5) ^& Chr(6) ^& String(18, vbNullChar) >> _zipIt.vbs
echo Set objShell = CreateObject("Shell.Application") >> _zipIt.vbs
echo Set source = objShell.NameSpace(InputFolder).Items >> _zipIt.vbs
echo objShell.NameSpace(ZipFile).CopyHere(source) >> _zipIt.vbs
echo wScript.Sleep 2000 >> _zipIt.vbs
CScript _zipIt.vbs %TEMPDIR% C:\someArchive.zip
pauseWrite access is required to the parent of the folder stored in TEMPDIR. As this is often not the case for the root of drive C TEMPDIR may have to be changed.
Write access is also required for the folder the .bat script is in (as it generates a file there).
Also, please note that the file extension for the compressed file must be .zip. Attempts to use another extension may result in a script error. Instead, generate the .zip file and rename it.
It is possible to zip files without installation of any additional software (I have tested it). The solution is:
Run this in a command-line window to create a ZIP file
named C:\someArchive.zip containing all files in folder C:\test3:
CScript zip.vbs C:\test3 C:\someArchive.zipWhere file zip.vbs contains:
' Get command-line arguments.
Set objArgs = WScript.Arguments
Set FS = CreateObject("Scripting.FileSystemObject")
InputFolder = FS.GetAbsolutePathName(objArgs(0))
ZipFile = FS.GetAbsolutePathName(objArgs(1))
' Create an empty ZIP file.
CreateObject("Scripting.FileSystemObject").CreateTextFile(ZipFile, True).Write "PK" & Chr(5) & Chr(6) & String(18, vbNullChar)
Set objShell = CreateObject("Shell.Application")
Set source = objShell.NameSpace(InputFolder).Items
objShell.NameSpace(ZipFile).CopyHere(source)
' Required to let the ZIP command execute
' If this script randomly fails or the ZIP file is not complete,
' just increase to more than 2 seconds
wScript.Sleep 2000I haven't tested it for paths and file names containing spaces. It may work if quotes are put around the command line parameters.
How it works: the built-in zip functionality in Windows (Windows XP and later?) is exposed through COM interfaces from the Windows shell, explorer.exe - that is the "Shell.Application" part. This COM interface can be used from a VBScript script because such a script can access COM components. To make the script fully self-contained it creates an empty ZIP file to get started (one could also create an empty ZIP file and copy it to the target system along with the VBScript script).
VBScript has been installed by default in every desktop release of Microsoft Windows since Windows 98.
CScript.exe is part of Windows Script Host.
Windows Script Host is distributed and installed by default on Windows 98 and later versions of Windows. It is also installed if Internet Explorer 5 (or a later version) is installed.
Windows 10 build 17063 or later is bundled with tar.exe which is capable of working with ZIP files from the command line.
tar.exe -xf archive.zipOr to create a ZIP archive:
tar.exe -a -cf Test.zip TestIf you are open to using PowerShell, zip capabilities are available in .NET 2.0 (PowerShell is .NET). Here's an a example (source) credit to Mike Hodnick:
########################################################
# out-zip.ps1
#
# Usage:
# To zip up some files:
# ls c:\source\*.txt | out-zip c:\target\archive.zip $_
#
# To zip up a folder:
# gi c:\source | out-zip c:\target\archive.zip $_
########################################################
$path = $args[0]
$files = $input
if (-not $path.EndsWith('.zip')) {$path += '.zip'}
if (-not (test-path $path)) { set-content $path ("PK" + [char]5 + [char]6 + ("$([char]0)" * 18))
}
$ZipFile = (new-object -com shell.application).NameSpace($path)
$files | foreach {$zipfile.CopyHere($_.fullname)}You can eliminate the risk of timing out during compression by polling for existence of the compression dialog window. This method also handles the user cancelling out of the compression window.
objShell.NameSpace(ZipFile).CopyHere(source)
' Wait for compression window to open
set scriptShell = CreateObject("Wscript.Shell")
Do While scriptShell.AppActivate("Compressing...") = FALSE WScript.Sleep 500 ' Arbitrary polling delay
Loop
' Wait for compression to complete before exiting script
Do While scriptShell.AppActivate("Compressing...") = TRUE WScript.Sleep 500 ' Arbitrary polling delay
LoopIf you are able to install the Resource Kit Tools, you will find a command line tool called COMPRESS that can create compressed archive files like zip.
Microsoft (R) File Compression Utility Version 5.00.2134.1
Copyright (C) Microsoft Corp. 1990-1999. All rights reserved.
Compresses one or more files.
COMPRESS [-r] [-d] [-z] Source Destination
COMPRESS -r [-d] [-z] Source [Destination] -r Rename compressed files. -d Update compressed files only if out of date. -zx LZX compression. -z MS-ZIP compression. -zq[n] Quantum compression and optional level (in range 1-7, default is 4). Source Source file specification. Wildcards may be used. Destination Destination file | path specification. Destination may be a directory. If Source is multiple files and -r is not specified, Destination must be a directory.There is a single, simple cmd.exe command for this (through PowerShell v5.0+).
To zip:
powershell Compress-Archive -LiteralPath 'C:\mypath\testfile.txt' -DestinationPath "C:\mypath\Test.zip"To unzip:
powershell Expand-Archive -LiteralPath "C:\mypath\Test.Zip" -DestinationPath "C:\mypath" -ForceSources:
Special thanks to @Ramhound.
3If on Windows 8 or Windows Server 2012 you'll have PowerShell and .NET 4.5, so you can do this:
zip.ps1 (usage: -directory <directory to zip up> -name <zip name>):
param ( [string]$directory, [string]$name
)
Add-Type -Assembly System.IO.Compression.FileSystem
[System.IO.Compression.ZipFile]::CreateFromDirectory($directory, $name, [System.IO.Compression.CompressionLevel]::Optimal, $false)zip.bat (if you need a helper to call PowerShell for you, the directory is first argument and the ZIP name second):
@Echo Off
powershell -ExecutionPolicy ByPass -Command "& '%~dpn0.ps1' -directory '%1' -name '%2'"'Keep script waiting until compression is done
Do Until objShell.NameSpace( ZipFile ).Items.Count = objShell.NameSpace( InputFolder ).Items.Count WScript.Sleep 200
LoopMultiple files / directories with simplified code.
cscript zip.vbs target.zip sourceFile1 sourceDir2 ... sourceObjNzip.vbs file
Set objArgs = WScript.Arguments
ZipFile = objArgs(0)
' Create empty ZIP file and open for adding
CreateObject("Scripting.FileSystemObject").CreateTextFile(ZipFile, True).Write "PK" & Chr(5) & Chr(6) & String(18, vbNullChar)
Set zip = CreateObject("Shell.Application").NameSpace(ZipFile)
' Add all files/directories to the .zip file
For i = 1 To objArgs.count-1 zip.CopyHere(objArgs(i)) WScript.Sleep 10000 'REQUIRED!! (Depending on file/dir size)
NextThis is a mutation of the accepted answer. I do a ton of automation tasks on up to thousands of files at a time, so I can't just sleep for 2 seconds and not care about it. I gleaned the workaround here, which is also similar to Jiří Kočara's answer here.
This will cause the destination folder to be pinged every 200 ms, which is approximately as fast as Microsoft says to check for file system updates.
Set parameters = WScript.Arguments
Set FS = CreateObject("Scripting.FileSystemObject")
SourceDir = FS.GetAbsolutePathName(parameters(0))
ZipFile = FS.GetAbsolutePathName(parameters(1))
CreateObject("Scripting.FileSystemObject").CreateTextFile(ZipFile, True).Write "PK" & Chr(5) & Chr(6) & String(18, vbNullChar)
Set shell = CreateObject("Shell.Application")
Set source_objects = shell.NameSpace(SourceDir).Items
Set ZipDest = shell.NameSpace(ZipFile)
Count=ZipDest.Items().Count
shell.NameSpace(ZipFile).CopyHere(source_objects)
Do While Count = ZipDest.Items().Count wScript.Sleep 200
LoopHere's my attempt to summarize built-in capabilities in Windows for compression and uncompression - How can I compress (/ zip ) and uncompress (/ unzip ) files and folders with batch file without using any external tools? - with a few given solutions that should work on almost every Windows machine.
As regards to the shell.application and WSH, I preferred the JScript one as it allows a hybrid batch/JScript file (with .bat extension) that does not require temporary files. I've put unzip and zip capabilities in one file plus a few more features.
As of Build 1803 (March 2018), Windows includes tar.exe at C:\Windows\System32\tar.exe. Tar can be used to create and extract zip files. Type tar /? for more info.
The Windows command line now provides the COMPACT command which, as far as I can tell, is native to Windows. That should meet the requirements requested unless I missed something.
